Keep the Linux Client up to date with the latest features.

The Microsoft Teams Linux client has significantly fallen behind the equivalent clients for Windows and Apple. Linux users only have a 2x2 grid (and no together mode), no blurred/custom background, no sharing of a single application window or pass-through audio, not able to administer breakout rooms, and various other functions have are available to other users. There is no meaningful entry for the Linux client on the Teams roadmap. The https://microsoftteams.uservoice.com/forums/555103-public/suggestions/40324324-keep-the-linux-client-up-to-date-with-the-latest-f has 4.799 votes (as of 1 April 2021) and yet no response at all from Microsoft. It is the only request in the first two pages of Microsoft Teams UserVoice requests that has no response from Microsoft.
