Oddly the widget displays correctly but when you click on any particular item in the widget it does not go to the Movie section of the relevant add on. Instead it either does not display anything or goes back to a screen further up in the add on. I tried manually creating the shortcut with, for example ActivateWindow(10025,"plugin://plugin.video.myaddon1/?action=movieNavigator",return) but that seems to click the back button on the addon screen not the movie button

It is doing this because the path you provided is incorrect. replace the " apostrophes with " That should work.

I find it much easy to favourite the place I want the widget to point to. Then use 'Custom widgets - Favourites' to add as widget
