You can add co-hosts to your hosting session by following these steps (subject to subscription plans):
- Have your co-host join the session like a normal player would.
- On the "Players" page in the left navigation of your session, find them in the players' section, and you should see "Co-host" next to their name.
You can share the URL to the page with them (Should look like this: https://www.livecase.com/app/host/XXXXXXX), or they can go to their Dashboard and select your session (Might need to page reload).
