how to stop character movement when finger is on GUI (lean touch)

I am new to unity and coding. i am using lean touch and i want to stop the movement of the player the moment my finger goes over an UI element. i want to ignore touches when IsOverGUI instead of StartOverGUI. how do i do this?

code: void OnEnable() { Lean.Touch.LeanTouch.OnFingerTap += HandleFingerTap; }

 void OnDisable()
 {
     Lean.Touch.LeanTouch.OnFingerTap -= HandleFingerTap;
 }

 void HandleFingerTap(Lean.Touch.LeanFinger finger)
 {
     if (finger.IsOverGui)
     {
         Debug.Log("You just tapped the screen on top of the GUI!");
     }
 }
