navigator.share throws NotAllowedError: Failed to execute 'share' on 'Navigator': Permission denied

[ZimnitskiYury]

Issue:

An error is thrown when attempting to use the navigator.share method within the Microsoft Teams Tab application:
Error: NotAllowedError: Failed to execute ‘share’ on ‘Navigator’: Permission denied

This error prevents the possibility of sharing files using the built-in Windows share functionality.

Question:

Is there a way to request permissions from the user or to add this permission to the app container to enable file sharing?

Hello @ZimnitskiYury - Could you please share the code base and repro steps, so that we can try it from our end?
Also, please the reference doc you are following.

@ChetanSharma-msft simpliest snippet:

if (microsoftTeams.app.isInitialized()) {
        const isShareSupported = 'share' in navigator && 'canShare' in navigator;
        if (isShareSupported) {
            navigator.share({text: 'test'});
        }
    }

expected result

A web-share Permissions Policy has been used to block the use of this feature, the window does not have transient activation, or a file share is being blocked due to security considerations.

Hi @ZimnitskiYury. This feature is actually not available in Teams JS. We have added a feature request for it to our backlog that we will review as part of our regular planning cycles, but I'm not able to provide any commitments or ETA at this time unfortunately. If there is any additional information on your use case or the value from your perspective that you would like to share I am happy to add it to the ticket for when we review it.
