How to get BindableAction working with mouse movement?

Have this setup to print "moved" when the player moves their mouse but isn't doing anything

local function FunctionToRun(actionName, inputState, inputObject)
    print("moved")
    print(actionName, inputState, inputObject 
end

game:GetService("ContextActionService"):BindAction("MoveToMouse", FunctionToRun, false, Enum.UserInputType.MouseMovement)
