Apply code to a gameObject with EventTrigger

I have a button for which i'd like to signify "attacking". I'm programming for android.

Basically i'd like to run this script, upon the touch of the attack button. Instead of using the F key to stop the code from rapidly repeating, i'm trying to figure out how to run an if statement for "if button is touched & !isAttacking" then go into the method.

  if (Input.GetKeyDown(KeyCode.F) && !isAttacking)
         {
             isAttacking = true;
             attackTimer = attackCD;
             Debug.Log("F Pressed");
 
             attackTrigger.enabled = true;
         }
 
         if (isAttacking)
         {
             if (attackTimer > 0)
             {
                 attackTimer -= Time.deltaTime;
             }
             else
             {
                 isAttacking = false;
                 attackTrigger.enabled = false;
             }
         }
