User id shown in push notifications instead of user name for mentions

[Davies-Owen]

Which packages are you using?

stream_chat_flutter, stream_chat_flutter_core

On what platforms did you experience the issue?

iOS

What version are you using?

stream_chat_flutter: 6.12.0
stream_chat_flutter_core: 6.11.0

What happened?

When a user is mentioned in a channel, the push notification received contains their user id instead of their username.
E.g. When the message Hello @John Smith is sent in the channel, the push notification body appears as Hello @1f589ed4-9148-11ee-82ff-f388544c506e

I would expect there to be a way to replace the ids of mentioned users with their usernames, similar to replaceMentions for Message. What I want is for the push notification body to say Hello @John Smith.

I found this comment from July 2022 saying that this is most likely a backend issue, but I couldn't find a place to file a ticket for the backend.

Steps to reproduce

I'm using Firebase to deliver push notifications.

1. Create a multi-user channel and subscribe two users to it. One of the two users should be subscribed from a phone with push notifications enabled.
2. From one of the user accounts, send a message with a mention, e.g. "Hello @John Smith"
3. The push notification received contains the user's id instead of the user's name

The missing Android dependencies should not be relevant, since I'm developing and testing for iOS.

We found out about this issue too during testing. The documentation did mention customizing the push template:

{
  "aps": {
    "alert": {
      "title": "New message from {{ sender.name }}",
      "body": "{{ truncate message.text 2000 }}"
    },
    "mutable-content": 1,
    "category": "stream.chat"
  },
  "stream": {
    "sender": "stream.chat",
      "type": "message.new",
      "version": "v2",
      "id": "{{ message.id }}",
      "cid": "{{ channel.cid }}"
  }
}

But it's doesn't change the mentioning id behavior. Can this ticket be escalated/forwarded to the backend team?
