click gameobject in specefic panel

Hi, I am working on a screen that has a list of friends. The problem is I want to click on this Game Object( 1 game object 1 friend) inside this specific panel ONLY (blue color). Before this , I tried, but it can clicked anywhere not specifically inside this panel. And this game object is a prefab. sorry, I am a newbie in Unity

  void Update () {
     if (Input.GetMouseButtonDown(0) )
     {
        

             try
         {
             Debug.Log("Clicked.");
             var ray = Camera.main.ScreenPointToRay(Input.mousePosition);
         
             Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
             Vector2 mousePos2D = new Vector2(mousePos.x, mousePos.y);

             RaycastHit2D hit = Physics2D.Raycast(mousePos2D, Vector2.zero);
            
             if (hit.collider.tag == "Panel1")
                 {
                 if (hit.collider.tag == "Friend")
                     Debug.Log("---> Hit: ");
                 }
                 Canvas.SetActive(false);
                 Canvas2.SetActive(true);
             
         }
         catch (Exception ex)
         {
             Debug.Log(ex);
         }

     }
 }
