Question: Launching multiple windows

See original GitHub issue

I am attempting to activate another window instance but was greeted with the following error.

Exception thrown at 0x00007FFC4FAA67AC (KernelBase.dll) in UI.exe: WinRT originate error - 0x80004005 : 'WinUI: Error creating second Desktop Window on the current process. No more than one Desktop Window is allowed per process.'.
Unhandled exception at 0x00007FFBAAE94BA8 (Microsoft.ui.xaml.dll) in UI.exe: 0xC000027B: An application-internal exception has occurred (parameters: 0x000001E4DDF05A10, 0x0000000000000005).

There error is clear… but I am not able to find how to properly open a new window with WinUI 3 Desktop. If someone could provide me with the proper approach I would appreciate it.
