feat: Element Call

[hanthor]

Description

Note: this is very much AI generated and not yet thoroughly tested

This implements the widget API inasmuch to get embedded Element Call to work. I'll probably maintain this as a fork, but I'm submitting a PR in case there's any desire for it

This works (barely). I know another implementation is in the works. But I want to keep recommending Cinny to people and the lack of calling is a deal breaker to many

Is it intended that you seem to be downgrading matrix-js-sdk here?

[hanthor]

No this was just me copy pasting stuff over from element web to get it to work. It can get updated.

The widget box needs a lot of improvement too. It could have a picture in picture and a fullscreen. I think fullscreen is necessary

[Sollace]

Yeah I would agree. I have also been looking at #2512 (which looked promising) and having not much luck running that one either. :/

I'd like to use cinny but the lack of video calling is a major blocker.

Have you looked at #2335 I'm currently using it and it seems to work well enough why is there three different versions of this?

[hanthor]

Because I didn't look at the open PRs

Closing in favor of #2599
