How do I use NotificationCenter in mac catalyst to detect and connect an external display?

I can successfully connect and show ExternalView() on the external display on IOS target.

However, mac catalyst is unable to detect the display connection in NotificationCenter.

How do I use NotificationCenter in mac catalyst to detect and connect an external display?

import Combine
import SwiftUI

@main
struct ScreensApp: App {

  @ObservedObject var externalDisplayContent = ExternalDisplayContent()
  @State var additionalWindows: [UIWindow] = []

  private var screenDidConnectPublisher: AnyPublisher<UIScreen, Never> {
    NotificationCenter.default
      .publisher(for: UIScreen.didConnectNotification)
      .compactMap { $0.object as? UIScreen }
      .receive(on: RunLoop.main)
      .eraseToAnyPublisher()
  }

  private var screenDidDisconnectPublisher: AnyPublisher<UIScreen, Never> {
    NotificationCenter.default
      .publisher(for: UIScreen.didDisconnectNotification)
      .compactMap { $0.object as? UIScreen }
      .receive(on: RunLoop.main)
      .eraseToAnyPublisher()
  }

  var body: some Scene {
    WindowGroup {
      ContentView()
        .environmentObject(externalDisplayContent)
        .onReceive(
          screenDidConnectPublisher,
          perform: screenDidConnect
        )
        .onReceive(
          screenDidDisconnectPublisher,
          perform: screenDidDisconnect
        )
    }
  }

  private func screenDidConnect(_ screen: UIScreen) {
    print("connected")
    let window = UIWindow(frame: screen.bounds)

    window.windowScene = UIApplication.shared.connectedScenes
      .first { ($0 as? UIWindowScene)?.screen == screen }
      as? UIWindowScene

    let view = ExternalView()
      .environmentObject(externalDisplayContent)
    let controller = UIHostingController(rootView: view)
    window.rootViewController = controller
    window.isHidden = false
    additionalWindows.append(window)
    externalDisplayContent.isShowingOnExternalDisplay = true
  }

  private func screenDidDisconnect(_ screen: UIScreen) {
    print("disconnected")
    additionalWindows.removeAll { $0.screen == screen }
    externalDisplayContent.isShowingOnExternalDisplay = false
  }

}
