Github bug report for OffWorldLive OBS Plugin

I've never used this but apparently this wrapper is useful for linux people: https://github.com/IsmaelMartinez/teams-for-linux

Have you tried an unofficial electron client?

I use https://github.com/IsmaelMartinez/teams-for-linux . It's "just" a wrapper around the PWA but a very decent one at that.

Unofficial and not Microsoft supported, but might be an alternative to Microsoft's official PWA. How do the two compare in your experience with them?

You can try the unofficial client Teams for Linux. It's available as a Flatpak and I didn't have any issues sharing my screen with it. https://github.com/IsmaelMartinez/teams-for-linux

This client works well for me: https://github.com/IsmaelMartinez/teams-for-linux

There is also: https://github.com/IsmaelMartinez/teams-for-linux

That always frustrated me, even more-so considering how that volunteer-built package I mentioned (https://github.com/IsmaelMartinez/teams-for-linux - an Electron build of the web app, nothing flashy but does the job just fine) does support screen sharing. I haven’t checked whether it supports backgrounds as I only use voice when on calls, but I’m guessing it does if the browser variant does.
