We are giving chat options in Teams through a custom Tab app.
Whenever i get new message in my Tab app, I would like to display the number of unread messages as a badge on the icon of the Tab app, just like the unread count in a Team channel, so the user doens't have to actively check the page, but is informed of new things to do through the badge.
I can't find a method on how to make this possible. Anyone can help me out? Is it even possible for a custom tab app?
