Macro or ShortCut Key for specific PopUp (SpaceMouse Button setup)

I’d like to set one of my SpaceMouse buttons to bring up my chosen PopUp (at this point, the same one I currently have set to my MiddleMouseButton) There’s an option to use a ShortCutKey on the 3DConnexion app.

So, if I can create a Macro and then a ShortCutKey for it, I could patch it to my SpaceMouse. Unless there’s a more direct way?
