Hey! I wrote this article. There is literally a description of the basic mechanics of the app starting at word 48 of the piece. I have no clue how you missed this!
> "After we exchanged pleasantries, Paul explained how the app works. There’s one global “room,” and when you join you start off on mute, but anyone can unmute themselves. When you open the app, it sends push notifications to everyone on the app, so they can join you and chat if they’re free."
I'm curious why this didn't work for you and what you would have wanted instead?
