I just wanted to share a pleasant experience I had yesterday.
I’ve started using Riot (a Matrix client) and it has nice integration for Jitsi Meet (on their own server). If you want to test it, I created a group at #jitsimeet:matrix.org .
When you have a direct chat or when in a group chat you can " add the Jitsi Meet widget " and it will show up as part of their web and desktop interfaces. On mobile there will be a small link to join an “ongoing conference call” which will launch Jitsi Meet and welcome multiple participants.
