Hi, thanks for the video. I could run this app with rails 7 and few modifications in import in video_chat_controoler.js locally without valid TURN server creds. Thought this was only in local. Then I deployed the app on Render at https://drkiq.onrender.com/rooms and here also it works without valid TURN serve credential? Hows that possible just with Redis/ActionCable/Stimulus? Whats the exact role of TURN server here since its running without it?
