How to allow player to interact with an actor object on mousehover/mouseclick

Hello, I am creating a building block interface with Cubes and Spheres, kind of like a level editor. I have the actors spawning on mouse click but would like to be able to move the shapes once they are spawned in on the click of the mouse. Is there a way to do it. Ive looked through the blueprints and haven’t seen one about mouse hover or mouse click.
Once the user clicks I would like to be able to add an xyz axis transform to the interface as well if anyone knows how to do that.

If anyone can help that would be great.

I think the reason nobody’s answer this yet, is because it’s a ‘whole thing’ to set this up.

Best to learn about how to get objects to respond to clicks first, which is blueprint interfaces:
