My Unreal app, is in the Oculus library. I can start it from the library. Setting up Oculus demo mode, I can select the app from a list. But then if I exit the app, it is not in the demo library (the demo library is empty). So I can't go back to my app. So demo mode means easy exit, no way back!?! (What I really need is simply users not to be able to get to Oculus home during an exhibition) using Unreal 4.19.
