Settings - Labs - Opt into the Video Calls Beta. You'll now have a new call option which has screensharing. Works very well.

I tried installing Matrix with the Element web interface a few days past, and was positively surprised by the VoIP and screenshare.
I always thought that Matrix was this dusty old legacy from times long forgotten, but once the images were spun up and the reverse proxy configured, it didn't take long to setup a small test community and invite a friend.
There's a beta option to enable screenshare in a room, but we found that you can screenshare in any voice room despite the setting. We only tested with simple visuals like videos and text documents, where we got small amounts of artifacting, so I'm not sure about the compression and throughput, but I hope it'll be enough for gaming.
