Detect touches on ui element

Question

I have a panel with the following script attached. All I want is to rotate the panel when moving my finger over it and open another menu when tapping it. The problem is that it works wherever I tap (blocking me from interacting with other buttons). So how could I detect touches on this specific object?

 ![public class RotateChY : MonoBehaviour {
     bool menuEnabled = true;
     bool moving = false;
 
     [SerializeField] float rotationSpeed = 1f;
 
     [SerializeField] GameObject chHolder;
     [SerializeField] GameObject chSelectionScreen;
     
     private void Start() {
         chHolder.SetActive(true);
         chSelectionScreen.SetActive(false);
     }
 
     private void Update() {
         if(Input.touchCount == 1){
             Touch screenTouch = Input.GetTouch(0);
             Debug.Log(EventSystem.current.currentSelectedGameObject + " is the current selected object");
 
             if(screenTouch.phase == TouchPhase.Moved) {
                 menuEnabled = false;
                 transform.Rotate(0, -screenTouch.deltaPosition.x * Time.deltaTime * rotationSpeed, 0);
                 } 
                 else if(screenTouch.phase == TouchPhase.Ended) {
                 if(menuEnabled) {
                     openChSelectScreen(true);
                 } else {
                     menuEnabled = true;
                 }
             }
         }
     }
 
     public void openChSelectScreen(bool val) {
         chHolder.SetActive(!val);
         chSelectionScreen.SetActive(val);
         Debug.Log("called with " + val);
     }
 }][1]

You could use an Event Trigger component and add an Event Like PointerEnter / Exit or Pointer Down / up https://docs.unity3d.com/2018.3/Documentation/ScriptReference/EventSystems.EventTrigger.html

I tried but for some reason it does not work... The Event Trigger component is not usually working in Unity Remote, only when I build the game, but still it's not working with my panel, just with the buttons.

 public class RotateChY : MonoBehaviour{
     bool menuEnabled = true;
     bool tapping = false;
 
     [SerializeField] float rotationSpeed = 1f;
 
     [SerializeField] GameObject chHolder;
     [SerializeField] GameObject chSelectionScreen;
     
     private void Start() {
         chHolder.SetActive(true);
         chSelectionScreen.SetActive(false);
     }
 
     private void Update() {
         if(tapping) {
             if(Input.touchCount > 0) {
                 Touch screenTouch = Input.GetTouch(0);
 
                 if(screenTouch.phase == TouchPhase.Moved) {
                     menuEnabled = false;
                     transform.Rotate(0, -screenTouch.deltaPosition.x * Time.deltaTime * rotationSpeed, 0);
                     } 
                     else if(screenTouch.phase == TouchPhase.Ended) {
                     if(menuEnabled) {
                         openChSelectScreen(true);
                     } else {
                         menuEnabled = true;
                     }
                 }
             }
         }
     }
 
     public void openChSelectScreen(bool val) {
         chHolder.SetActive(!val);
         chSelectionScreen.SetActive(val);
     }
 
     // public void OnPointerDown(PointerEventData eventData) {
     //     tapped = true;
     //     Debug.Log("tapping");
     // }
     // public void OnPointerUp(PointerEventData eventData) {
     //     tapped = false;
     //     Debug.Log("not tapping");
     // }
     public void pointerDown() {
         tapping = true;
         Debug.Log("tapping");
     }
 
     public void pointerUp() {
         tapping = false;
         Debug.Log("not tapping");
     }
 }

Apparently my taps are not detected on the built version...
