MAUI - After Launcher.OpenAsync, app returns to main window

Question

I've got an application that has structure like that:

Main View with menu --press button--> List View --select item from listview--> Modal window.

Each modal window contains button, that launches youtube video:

await Launcher.Default.OpenAsync(new Uri($"vnd.youtube://{link}"));

Same behaviour if i try to open document:

await Browser.Default.OpenAsync(new Uri(link.ToString())

Even though youtube video opens, when i go back to application it is back to Main View. How can i force app to stay in the same view when Launcher is executed?

Note: It did work as intended on Xamarin.Forms...

EDIT: Button/Image code in xaml:

<Image Grid.Row="9" Grid.Column="1" HeightRequest="50" WidthRequest="50" HorizontalOptions="Start" IsVisible="{Binding HasDocumentLink}" Source="pdf_icon" >
 <Image.GestureRecognizers>
   <TapGestureRecognizer Tapped="Document_Tapped" CommandParameter="{Binding BoardGame.TutorialLink}" NumberOfTapsRequired="1" />
 </Image.GestureRecognizers>
</Image>

And full method in view model:

private void Document_Tapped(object sender, EventArgs e)
{
  var link = ((TappedEventArgs)e).Parameter;
  Browser.Default.OpenAsync(new Uri(link.ToString()), BrowserLaunchMode.SystemPreferred);
}

EDIT2: On request, also ItemTemplate for opening modal window:

<Grid.GestureRecognizers>
  <TapGestureRecognizer Command="{Binding BindingContext.TapCommand, Source={x:Reference BoardGamesView}}" CommandParameter="{Binding .}" NumberOfTapsRequired="1"/>
 </Grid.GestureRecognizers>

Viewmodel:

private void OnItemTapped(BoardGame boardGame)
{
 App.Current.MainPage.Navigation.PushModalAsync(new BoardGamePage(boardGame), false);
}
