How can I track Right and Left on the Thumbstick on the controller?

local LeftAction: any = ContextActionService:BindAction("Left", Left, false, Enum.KeyCode.A, Enum.KeyCode.Left, Enum.KeyCode.Thumbstick1)
local RightAction: any = ContextActionService:BindAction("Right", Right, false, Enum.KeyCode.D, Enum.KeyCode.Right, Enum.KeyCode.Thumbstick1)

If you see these, I have Thumbstick1 for Xbox KeyCode, however, I do not know how to track Left and RIght. Do you know how?

I currently do not have an MFI Controller to test with yet. If you can help me out, that will be appreciated! Thanks, WE
