Presenting immersive content in UIKit app

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?
