True! I've been doing this for years on Linux. I use a dedicated Chromium instance in app mode:

  /usr/bin/chromium --ozone-platform=wayland --enable-features=UseOzonePlatform,WaylandWindowDecorations,WebRTCPipeWireCapturer --user-data-dir=/home/myuser/.config/chromium-ilri --app=https://teams.microsoft.com

Works incredibly well (put this in a `.desktop` file with `Exec=` and you can launch it via your desktop's launcher). Some of the settings may not be needed anymore, as Chromium has come a long way in terms of Wayland support. I use Firefox for everything else, but haven't tried Teams there.
