Help on recording

I want to start recording the call right after a user creates a room (https://i.imgur.com/isTCbNz.png) and join (https://i.imgur.com/gSGuK6A.png).

Any advices on how to do this?

ALWAYS : the session will be automatically recorded from the moment the first participant starts publishing.
