How can I set the position of an app window on the screen for macOS with Swiftui?

I am trying to determine how to set the initial position of an app window for macOS. I have tried using NSViewRepresentable and .setFrameTopLeftPoint with no success. Is my syntax incorrect to achieve the desired results or should I be looking at some other method?

struct WindowAccessor: NSViewRepresentable {
    @Binding var window: NSWindow?
    
    func makeNSView(context: Context) -> NSView {
        let view = NSView()
        view.window?.setFrameTopLeftPoint(CGPoint(x: 600, y: 400))
        DispatchQueue.main.async {
            self.window = view.window
        }
        return view
    }
    
    func updateNSView(_ nsView: NSView, context: Context) {}
}

and

    var body: some Scene {
        WindowGroup {
            ContentView()
                .background(WindowAccessor(window: $window))
        }
