The picture of a group chat in Teams has so far been created via the participants of the chat.
Members of the chat can now insert a predefined image, upload a user-defined image (jpg and png), or use an Emoji.
After the change, Teams notes which account has changed the image and shows the custom image.
Update from 11 May 2024:
The rollout should be completed by the end of May.
