Show Help in Apple Help Viewer

I’ve implemented some Help Pages for my app and using App Wrapper Mini they are indexed and searchable and all that fancy stuff.
But, how do I create a menuitem that opens my help pages in Apple Help Viewer without searching first?

This example image is from App Wrapper Mini.

Looking into macosLib at the moment. There is Cocoa.NSApplication.ShowHelp but I have no clue on how to work with it :confused:
Ideas?
