Show-TUIDesigner should initialize the [Terminal.Gui.Application]

[DataTraveler1]

Is your feature request related to a problem? Please describe.

Yes. The problem is that it's not clear that the below command must be issued in order for Show-TUIDesigner to function as shown in the documentation.

[Terminal.Gui.Application]::Init()

Describe the solution you'd like

Upon being invoked, Show-TUIDesigner should check for the presence of the [Terminal.Gui.Application] class and initialize it automatically

Describe alternatives you've considered

Initialize the class manually before executing Show-TUIDesigner (pictured further below)

Additional context

This applies to PowerShell Core 7.2.6

Note: if manually initializing the class fails, try importing the PowerShellProTools module

Forgot to mention, the immediate way to determine if the TUI designer is "working as expected" is if you can drag the control around onto the canvas (as shown in the gif in the documentation). You will not be able to drag it around with the mouse if the class is not initialized.
