Hi, I have one question. How do I issue MagnifyGesture's onChange event in the visionOS simulator? I have tried various operations, but the onChange event does not work.

@main
struct WorldApp: App {
   @State private var currentStyle: ImmersionStyle = .mixed
   var body: some Scene {
        ImmersiveSpace(id: "solar") {
            SolarSystem()
                .simultaneousGesture(MagnifyGesture()
                    .onChanged { value in
                        let scale = value.magnification
                        if scale > 5 {
                            currentStyle = .progressive
                        } else if scale > 10 {
                            currentStyle = .full
                        } else {
                            currentStyle = .mixed
                        }
                    }
                )
        }
        .immersionStyle(selection:$currentStyle, in: .mixed, .progressive, .full)
   }
}

Thanks.

Convert the 2D magnify gesture to a 3D one by modifying it with a "target entity" modifier.

There are few. The following option enables the gesture on all entities in the scene.

MagnifyGesture().targetedToAnyEntity()

Do you mean how to trigger a gesture in the simulator? You can try holding down the Option key and then moving your cursor.
