The experimental Element X client implements it only for mobile, and on desktop you must use the separate Element-call client.
Everything else still uses jitsi.
Like I said, it’s in development. Yes, you can jump some hoops to use it, but jitsi in element (and other matrix clients) is sticking around for a while yet.
Mine went bye-bye a while ago.
I initially installed linux on an additional smaller ssd. I recently set out to swap that setup around, so that windows gets to be on the smaller drive.
Except that after moving Endeavour to the big ssd… I just didn’t bother with setting up windows again. Haven’t needed it yet.
