Get Ref to what is in Socket?

How is it possible to get a reference of the object that the character bp is holding, i.e to get the object (skeletal mesh or actor bp) that is in a socket on the character bp?

Engine call such actors “attached” search based on that keyword

I’m having trouble spawning this node. How do I get access to it?
I am using AttachActorToComponent inside the actor BP, then I attach it to a new socket inside my Character BP using the same node.
