Proper "Twin Stick" rotation with a paper character

Hi everyone. I’m trying to make a twin stick shooter with 2d sprites.
My older brother and I love games like “Smash TV,” and “Enter the Gungeon,” and that is the style game I’m going for. I’ve got sprites made and imported and most of the control bp set up, but I cannot; for the life of me, figure out how to properly use the right stick to fire and rotate.

I can get the left stick to control movement, but I can’t get the right stick to control the 8 directions. I’ve spent three days looking online at videos and reading, but they all seem to only show twin stick controls for an animated character… Not a 2d Sprite with 8 directional Flipboard.

I would greatly appreciate any help!!!
