How do I use is mouse button down?

Hi! So I’m trying to figure out how to use “is mouse button down” to destroy the static mesh component of my actor when click on it. I have 4 random spawners releasing different colour balls and the aim is to destroy one when I click on it and then it and I get a score based on whichever one is destroyed. If you even know any good tutorials that explain a way to click and destroy using the “is mouse button down” that would be great thanks.
