Encountered the same issue, any update on this?

How do you run Apple Vision Pro destination on the iPad? I'm not able to see a way to do that. Probably you're just running a RealityKit app on iPad?

I have the exact same question, any updates so far? Bing / ChatGPT was hallucinating and told me that it's possible with App Groups or a custom Info.plist key "NSGroupActivitiesIdentifier"
