SwiftUI SceneView not receiving tap gestures on MacOS

In an Xcode MultiPlatorm App, the following works as expected (detecting tap gestures) in iOS simulator, but not when compiled and run on "My Mac" -- on Mac OS the view doesn't seem to get any clicks.

Does anyone know a way to get this to work?

One of the reasons

import SwiftUI
import SceneKit

class RenderDelegate: NSObject, SCNSceneRendererDelegate {
    var lastRenderer: SCNSceneRenderer!
    func renderer(_ renderer: SCNSceneRenderer, updateAtTime time: TimeInterval) {
        lastRenderer = renderer
    }
}

class Model: ObservableObject {
    let scene = SCNScene()
    let renderDelegate = RenderDelegate()
}

struct ContentView : View {
    @ObservedObject var model = Model()
    @State private var pointOfView = "distantCamera"

    init() {
        let sphereGeometry = SCNSphere(radius: 0.05)
        
#if os(iOS) || os(watchOS) || os(tvOS)
        sphereGeometry.firstMaterial?.diffuse.contents = UIColor.red
#else
        sphereGeometry.firstMaterial?.diffuse.contents = NSColor.red

#endif

        let sphereNode = SCNNode(geometry: sphereGeometry)
        sphereNode.position = SCNVector3Make(0.0, 0.0, 0.0)
        model.scene.rootNode.addChildNode(sphereNode)
    }
    
    var body: some View {
        ZStack {
            SceneView(
                scene: model.scene,
                options: [ .allowsCameraControl ],
                delegate: model.renderDelegate
            ).onTapGesture {print("tap")}
            
        }
        .padding()
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
