In my .NET Maui hybrid application using Blazor, I have a requirement: when a user attempts to navigate back or presses the back button in the mobile app, I need to display a confirmation popup asking if they want to close the application before proceeding to close the app. I tried below code in App.xaml.cs, but its showing pop up when opening the application again. I want to know which method to be called just before closing the application.

 public partial class App : Application
 {
     private IAudioPlayer _audioPlayer;
     private IAudioManager _audioManager;
     private NavigationManager NavigationManager;
     public bool isPlaying = true;
     public App(IAudioManager audioManager)
     {
         InitializeComponent();
         MainPage = new MainPage();
         _audioManager = audioManager;
     }
     protected override Window CreateWindow(IActivationState? activationState)
     {
         Window window = base.CreateWindow(activationState);

         window.Created += (s, e) =>
         {
             // Custom logic
         };

         window.Destroying += (s, e) =>
         {
             _audioPlayer.Stop();
         };

         window.Deactivated += (s, e) =>
         {
             if (_audioPlayer != null)
             {
                 _audioPlayer.Stop();
             }
         };
         
         window.Deactivated += Window_Deactivated;
        
         return window;

     
     }

  }

I tried to do something like this in App.xaml.cs but with after closing the app it calling so that opening again my pop is showing.
