How can I use Google Play Services Event system?

I have a script that makes the player jump and I want that every time that the player jumps, the event that I have created increases by 1 to know how many jumps have been done in my game.

I have created the Event in my Google Play Developer Console but I don't how to Implement it to my code. I have already read this: https://developers.google.com/games/services/common/concepts/quests#event_basics

  void Update () {
             if(Input.GetMouseButtonDown(0) && !EventSystem.current.IsPointerOverGameObject(0)){
                 if(corrent){
                     // Hacemos que salte si puede saltar
                     if(alTerra || !dobleSalt){
                         GetComponent<AudioSource>().Play();
                         GetComponent<Rigidbody2D>().velocity = new Vector2(GetComponent<Rigidbody2D>().velocity.x, forçaSalt);
     
     //the increase code should go here I think
     
                         //rigidbody2D.AddForce(new Vector2(0, forçaSalt));
                         if(!dobleSalt && !alTerra){
                             dobleSalt = true;
                         }
                     }
                 }else{
                     corrent = true;
                     NotificationCenter.DefaultCenter().PostNotification(this, "PersonatgeComençaACorrer");
     
                 }
             }
         }
