Just replace YOUR_ROOM_ID and YOUR_KEY with your own values and open the link in two Chrome/Canary tabs. If you remove e2eKey from the URL params in one of the tabs and reload it, you will just listen to and see garbage.
Great work @vpalmisano. The demo is working like a charm in my Google Chrome stable (89.0.4389.90). I am running chrome on Ubuntu 20.04 LTS.
While trying the demo for a couple of times initially, the demo crashed my chrome with error code as SIGSEGV. It only happened initially for 3 to 4 times and after that it started working fine.
Can there be a logic for such a behavior of my chrome?
