Using Maps in App Intents

I want to use MapKit with App Intents, but the map does not show up.(See attached image)

Can anyone help me solve this?

import SwiftUI
import MapKit

struct ContentView: View {
  @State private var region = MKCoordinateRegion(
    center: CLLocationCoordinate2D(latitude: 37.334_900,
                    longitude: -122.009_020),
    latitudinalMeters: 750,
    longitudinalMeters: 750
  )
   
  var body: some View {
    VStack {
      Map(coordinateRegion: $region).frame(width:300, height:300)
        .disabled(true)
    }
  }
}

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

import AppIntents
import SwiftUI
import MapKit

struct test20220727bAppIntentsExtension: AppIntent {
  static var title: LocalizedStringResource = "test20220727bAppIntentsExtension"
   
  func perform() async throws -> some IntentResult {
    return .result(value: "aaa", view: ContentView())
  }
}

struct testShortcuts:AppShortcutsProvider{
  @available(iOS 16.0, *)
  static var appShortcuts: [AppShortcut]{
    AppShortcut(
      intent: test20220727bAppIntentsExtension(),
      phrases: ["test20220727bAppIntentsExtension" ]
    )
  }
}
