How to change the visibility of an actor after button press

Hi guys so im prototyping an simple character select system.

What i want is to be able to click one of the characters in the menu below and then it would swap the mesh out to the correct one. i managed to get it working with key inputs.

Might want to look at the OnClicked events for the objects or give a bit more information on your setup? Are you clicking an actor with the mouse or is this a menu system?

the blueprint you see is the level blueprint.
its a menu system so you click on the icon of the character and then the mesh you see will change to the right mesh.
i was trying around in onclicked but i wasnt able to get an refrence to that specific character is there meaby a way to get an actor reference in umg
