Bot to show the transcript of the meeting using Microsoft Graph API.

This is a sample application which demonstrates how to get Transcript using Graph API and show it in the task module.

Included Features

• Bots
• Adaptive Cards
• Task Modules
• RSC Permissions

Interaction with app

Prerequisites

• Microsoft Teams is installed and you have an account (not a guest account)
• NodeJS
• dev tunnel or ngrok latest version or equivalent tunneling solution
• M365 developer account or access to a Teams account with the appropriate permissions to install an app.
• Teams Toolkit for VS Code or TeamsFx CLI

Run the app (Using Teams Toolkit for Visual Studio Code)

The simplest way to run this sample in Teams is to use Teams Toolkit for Visual Studio Code.

1. Ensure you have downloaded and installed Visual Studio Code
2. Install the Teams Toolkit extension
3. Select File > Open Folder in VS Code and choose this samples directory from the repo
4. Using the extension, sign in with your Microsoft 365 account where you have permissions to upload custom apps
5. Select Debug > Start Debugging or F5 to run the app in a Teams web client.
6. In the browser that launches, select the Add button to install the app to Teams.

If you do not have permission to upload custom apps (sideloading), Teams Toolkit will recommend creating and using a Microsoft 365 Developer Program account - a free program to get your own dev environment sandbox that includes Teams.

Setup

1. Register a new application in the Microsoft Entra ID – App Registrations portal.
   • Log in to the Azure portal from your subscription, and go to the "App registrations" blade here. Ensure that you use a tenant where admin consent for API permissions can be provided.

• Click on "New registration", and create an Azure AD application.

• Name: The name of your Teams app - if you are following the template for a default deployment, we recommend "App catalog lifecycle".

• Supported account types: Select "Accounts in any organizational directory"

• Leave the "Redirect URL" field blank.

• Click on the "Register" button.

• When the app is registered, you'll be taken to the app's "Overview" page. Copy the Application (client) ID; we will need it later. Verify that the "Supported account types" is set to Multiple organizations.

• On the side rail in the Manage section, navigate to the "Certificates & secrets" section. In the Client secrets section, click on "+ New client secret". Add a description for the secret and select Expires as "Never". Click "Add".

• Once the client secret is created, copy its Value, please take a note of the secret as it will be required later.

• At this point you have 3 unique values:

  • Application (client) ID which will be later used during Azure bot creation
  • Client secret for the bot which will be later used during Azure bot creation
  • Directory (tenant) ID We recommend that you copy these values into a text file, using an application like Notepad. We will need these values later.

• Under left menu, navigate to API Permissions, and make sure to add the following permissions of Microsoft Graph API > Application permissions:

  • OnlineMeetings.Read.All
  • OnlineMeetingTranscript.Read.All

Click on Add Permissions to commit your changes.

• If you are logged in as the Global Administrator, click on the Grant admin consent for %tenant-name% button to grant admin consent else, inform your admin to do the same through the portal or follow the steps provided here to create a link and send it to your admin for consent.

• Global Administrator can grant consent using following link: https://login.microsoftonline.com/common/adminconsent?client_id=<%appId%>

2. Setup for Bot

   • In Azure portal, create a Azure Bot resource.

   • Ensure that you've enabled the Teams Channel

   • While registering the bot, use https://<your_tunnel_domain>/api/messages as the messaging endpoint.

   • Create new Azure Bot resource in Azure.

   • Select Type of App as "Multi Tenant"

   • Select Creation type as "Use existing app registration"

   • Use the copied App Id and Client secret from above step and fill in App Id and App secret respectively.

   • Click on Create on the Azure bot.

   • Go to the created resource, navigate to channels and add "Microsoft Teams".

   • Ensure that you've enabled the Teams Channel NOTE: When you create app registration, you will create an App ID and App password - make sure you keep these for later.

3. Setup NGROK

1. Run ngrok - point to port 3978

   ngrok http 3978 --host-header="localhost:3978"

   Alternatively, you can also use the dev tunnels. Please follow Create and host a dev tunnel and host the tunnel with anonymous user access command as shown below:

   devtunnel host -p 3978 --allow-anonymous

4. Setup for code

• Clone the repository

  git clone https://github.com/OfficeDev/Microsoft-Teams-Samples.git

• Update the .env configuration for the bot to use the MicrosoftAppId and MicrosoftAppPassword and MicrosoftAppTenantId and AppBaseUrl and UserId (Note that the MicrosoftAppId is the AppId created in step 1 , the MicrosoftAppPassword is referred to as the "client secret" in step 1 and you can always create a new client secret anytime., MicrosoftAppTenantId is reffered to as Directory tenant Id in step 1, AppBaseUrl is the URL that you get in step 3 after running the tunnel, UserId of the user used while granting the policy in step 5).

• In a terminal, navigate to samples/meetings-transcription/nodejs

• Install modules

  npm install

• Run your bot at the command line:

  npm start

5. Allow applications to access online meetings on behalf of a user
   • Follow this link- Configure application access policy

• Note: Copy the User Id you used to granting the policy. You need while configuring the .env file.

6. Setup Manifest for Teams

• This step is specific to Teams.

  • Edit the manifest.json contained in the ./appManifest folder to replace your Microsoft App Id (that was created when you registered your app registration earlier) everywhere you see the place holder string {{Microsoft-App-Id}} (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json)
  • Edit the manifest.json for validDomains and replace {{domain-name}} with base Url of your domain. E.g. if you are using ngrok it would be https://1234.ngrok-free.app then your domain-name will be 1234.ngrok-free.app and if you are using dev tunnels then your domain will be like: 12345.devtunnels.ms.
  • Zip up the contents of the appManifest folder to create a manifest.zip (Make sure that zip file does not contains any subfolder otherwise you will get error while uploading your .zip package)

• Upload the manifest.zip to Teams (in the Apps view click "Upload a custom app")

  • Go to Microsoft Teams. From the lower left corner, select Apps
  • From the lower left corner, choose Upload a custom App
  • Go to your project directory, the ./appManifest folder, select the zip folder, and choose Open.
  • Select Add in the pop-up dialog box. Your app is uploaded to Teams.

Note: If you are facing any issue in your app, please uncomment this line and put your debugger for local debug.

NOTE: If you are not getting option to start transcript. Make sure it is enabled from Teams Admin center. Under Meetings -> Meeting Policies -> Applied policy(Default is Global)-> Recording & Transcription -> Transcription

Running the sample.

1. Schedule the meeting and add Meeting Transcript Bot from Apps section in that particular scheduled meeting.

2. Once meeting started, start the Transcript for the meeting.

4. Once the Meeting ended, Meeting Transcript Bot will sent a card having a button to open task module.

5. After clicking on View Transcript button, you will see the recorded Transcript in the opened Task Module.

Interacting with the bot.

• After uploading the manifest add the bot into meeting.
• Join meeting and Start Transcript
• Once done, leave the meeting.
