Make the player stay under the mouse pointer

I’m brand new to Unreal Engine Game Development. I have a very simple game I’m trying to develop that has just a top-down view so movement will only be on the flat plane. I want the player pawn (I hope that is the right term) to move with the mouse pointer. This is really for a touch screen. I am trying to learn so I started with probably the wrong template. I’d like to know how to do it “from scratch.”

Thanks very much in advance.
