How to use PopupService to show popup in ViewModel?
I have ViewModel with:

[RelayCommand]
private async Task ShowPopupAsync(object sender)
{
     var popup = popUpService.GetPopup(sender);
     popupService.ShowPopup(popup);
}

PopUpService:

public Popup GetPopup(object sender)
{
    var button = sender as ImageButton;
    var popup = new CustomPopup
    {
        Anchor = button
    };

    return popup;
}

And I have error in line popupService.ShowPopup(popup);:

System.Collections.Generic.KeyNotFoundException: 'The given key 'CommunityToolkit.Maui.Views.Popup' was not present in the dictionary.'

When I use Shell.Current.ShowPopup(popup); everything works but I don’t want to use Shell in my ViewModel.
