Proper way to leave a session

I am working on setting up a simple networked lobby. I can’t figure out how to have the client only back out of the lobby without disturbing the server or other clients. I use create session and join session nodes to connect which works fine. To leave I use destroy session and open the main menu level. The odd part is it works fine on the client but the hosting player has the screen go black. My question is whats the proper flow of leaving a session as a connected player and allowing other players to continue playing.

Any help is welcome
