Spawning a Variable class actor blueprint

I’m trying to spawn a blueprint based on a changing class actor variable. I then set that as an Actor Variable but i cant figure out how to trigger that spawned blueprints function. also the exposed parameters of the blueprint don’t show up in the spawn actor function.

Node structure below
the SceneA Variable acts the way i want and gives me the options i want but Set01 is the general way i need to interact with it.
I don’t always know what blueprint will be spawning or what exposed parameters the blueprint will have, but i need to be able to set those parameters on spawn.
All the blueprints will all have the same event names
