Hookmark 7 Hook to PDF not working

I’ve upgraded Hookmark to 7.0 with Setapp, and confirmed it is on 7.0. Control-CMD-P does nothing. And I don’t see any other way to invoke it without this shortcut, and no way to alter the shortcut (I suppose it’s possible there could be a shortcut conflict with another app, but no way to check or change that)… Looks like a great feature- thanks.
