Equilvant to MouseMovement for ThumbStick input?

Hello, everyone.

I'm currently trying to figure out how I can port over my custom camera script to work on a gamepad, however, when I use ThumbStick2, the camera only moves a tiny bit before snapping back to the center.

I think all I would need is the Enum equivalent to MouseMovement for the thumbstick input. Any help would be greatly appreciated.
