Changing click key and adding an effect

So I’m starting to make a MOBA game to release in a year or two. I want to largely base my MOBA of of the already pre-constructed top view template that unreal engine provides at first. I was wondering how to change the person from moving to the location of a left click to a right click and how to add an particle effect when the click happens. Iv’e looked a bit on the forums and and on YouTube and not have found any help. Any help will be largely appreciated! Thanks in advance!

To change to right mouse, change in project settings

How did you get the other nodes beneath it, mine only show up with two? And it seems the youtube video link is broken.
