Support Screen Sharing in web browser
The web app doesn't support screen sharing. This would be a huge setback for the linux users as we don't have a native Linux client.

A Linux client is now available. Screen sharing is supported, but remote control (and several other features) are not. Go to https://www.microsoft.com/en-us/microsoft-365/microsoft-teams/download-app on a Linux system.
