On the desktop app (Version 1.3.00.25560 64-bit, installed from Microsoft's msteams yum repo)
on Fedora Linux 33 emojis are only displayed as black-and-white symbols. These are very hard to read (see screenshot). In the browser and in other apps like the gnome terminal emojis are colorful and nice. I would like colorful emojis in the Teams desktop app too.

Sidenote: I'm using default system fonts everywhere, and Teams has no option to change the font type.
