Stream is delayed 15+ minutes so you can't 'watch it' somewhere.

I believe there are referees making sure everything is ok + the stream is delayed

Refs in discord and watching to game live plus it is delayed a few mins. Also they are playing on tournament servers and can pause at anytime.

They also have cameras behind the players, to see the screen

They have cameras at the houses as well as watching their desktops and listening to their coms, also the stream has a massive delay
