To invite friends to a studio simply move to the shared sequencer window and click the Invite button.
Then, simply search by name or email and invite others to your project.
You'll know you're connected when you see their profile picture appear at the top of the shared sequencer, and you'll see their mouse cursor move around.
To accept an invitation simply click on "Accept" when the invitation banner appears at the top of the sequencer window. After accepting, a second banner will ask whether or not you want to move to the new studio right away.
