How to change skeletal mesh of an actor via custom event?

I am making a hero selection menu that contains the hero icons of different characters the player can play as. Once I click on an icon I want a new widget to open and the selected character’s skeletal mesh to appear on the actor. So I made a custom event that would change the skeletal mesh of the actor, but it seems that the custom event needs a connection to something but I don’t know what, please help.I am not even sure if the method I am using is correct.


Where is the ChangeToAurora function. It’s need a reference for this.
