RM559612Microsoft Teams: Badging updates help find messages that count in the chat list

Microsoft Teams displays a badge on the app bar that reflects activity across chats and channels. Now, it’s easier to find and clear the messages behind that badge. Unmuted chats show a purple indicator when they affect the badge, while mentions, followed threads, and tag mentions display a purple number indicating how many items within are unread and part of the count.
