I have a UIKit app and would like to provide spacial experience when run on VisionOS. I added VisionOS support, but not sure how to present an immersive view. All tutorials are in SwiftUI, but my app is in UIKit. This is an example from a SwiftUI project, but how how do I declare this ImmersiveView in UIKit? struct VirtualApp: App { var body: some Scene { WindowGroup { ContentView() }.windowStyle(.volumetric) ImmersiveSpace(id: "ImmersiveSpace") { ImmersiveView() } } } and in UIKit how do I make the call to open the ImmersiveView?
