User Profile

I'd like to implement a fully immersive space that's experienced by multiple Vision Pro users simultaneously via SharePlay. To do this, the multiple Vision Pro users will join a SharePlay-enabled visionOS window that has a button to enter a fully immersive space, which is also SharePlay-enabled. I tried following the WWDC sessions and docs, but they don't provide enough detail about integrating SharePlay into an existing window and immersive space. How can I adjust my SharePlay code so it makes my visionOS window + fully immersive space SharePlay-able? Please see existing code below for a SharePlay visionOS widow, thank you. P.S.
