I'm very new to this so go easy on me lol.
I'm making a 3rd person game using the default 3rd person template, but I would like to toggle (by pressing gamepad L3) between that standard movement and a physics-based ball-rolling mechanic. I found a tutorial on YouTube for the ball mechanics that's easy to follow, but I'm having trouble understanding how to create a toggle that switches control modes.

I've created an Input Action (IA_ToggleBall) and mapped it to the IMC, but I'm unsure how to go about the node placements...
I tried asking the Ai Assistant, but I'm not even sure if I'm asking it the right questions because I'm so new to this space, so I'm hoping to get some help from any kind soul that's willing to share some knowledge.
