End-to-end encryption using Insertable Streams

We have tried last night a latest commit 130a1d
eg. that includes draft support for E2EE handling through insertable streams.
We have used Chrome Canary 84+, enabled Experimental Web Platform features

We can confirm insertable stream is working through example

During the Jitsi conference call over Videobridge we found that we don’t have sound and video. Just blank black screens. We see our own video only.

I know that work is still in the progress. But should it work to some degree?

Thank you
