We are using the MAUI CommunityToolkit to open a popup as described here https://learn.microsoft.com/en-us/dotnet/communitytoolkit/maui/views/popup

How can we on Android listen to the back button and close the Popup whenever the user clicks the Back button (hardware button on device). We have tried this method as described here Reset xamarin.forms.shell to initial page on back button but cannot get that to work on a CommunityToolkit popup.
