Can't make ImmediateSuperInteraction work on NPC sims

I have this interaction that allows to change the Vampire Dark Form via shift+click cheat menu.

It works perfectly fine on my active sim, but - althouth showing up - not on the NPCs.
I do understand it has something to do with the "Actor", because it always changes the active sim when trying it out on an NPC. But I can't figure out the solution.

This is only the "change into" part, since it would work the same in principal the other way around.

Please ignore the global testing, still figuring that out, but could anybody point me in the right direction?
