Enable multi-user collaboration capabilities in the visionOS App
summary
Shows how SharePlay (implemented with the GroupActivities framework) creates real‑time, bidirectional sessions using activity/session/messenger, demonstrated by a Jenga‑style demo where block positions sync across devices and platforms. visionOS adds per‑window sharing and SpacePersona templates (spatial Persona still beta), while constraints include a 100KB message limit, one active session per FaceTime with no owner, and debugging requiring identical bundle IDs or a minimal iOS/VisionOS loop. Code and a demo plugin approach for Unity are available on GitHub; the demo works.
