Could we please get a XAML Islands example for WPF .Net 5 using CsWinRT

I'm assuming we should be using CsWinRT when accessing UWP APIs from WPF .Net 5.  That said, it doesn't look like XAML Islands are supported yet (not sure since there are no examples out there).

Could you please clarify how XAML Islands are to be used in a WPF .Net 5 app that uses CsWinRT.
