Position and orientation of a window in an immersive space

Is it possible to retrieve the position and orientation of a window that is opened in an immersive space?

The following code:

struct MyWindow: View {
    var body: some View {
        VStack {
            Text("Hello")
        }
        .onGeometryChange3D(for: Point3D.self) { proxy in try! proxy
                .coordinateSpace3D()
                .convert(value: Point3D.zero, to: .worldReference)
        }
        action : { point in
            print(point)
        }
    }
}

seems to work for the position, but I also need the orientation.
