We use live share a lot for pair programming. It works okayish, but the built-in terminal is borderline useless for guests due to its very poor handling of different view port sizes. I recommend to instead let your pair in through SSH (a reverse proxy, like ngrok, is useful), and then sharing a tmux session.
