How to attach a pre attached actor to a different actor?

I believe that’s correct, you detach the object from one socket and attach it to the other character’s socket.

At the bottom of this page you can see the attach nodes, there are detach nodes as well.

I have an actor attached to my right hand socket and I want that when my character moves to a box trigger, it should detach the object from his hand and attach that same object to some other actor.
