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: Events  |  Play Games Services  |  Google for Developers

 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");
    
    			}
    		}
    	}

Hello? Noone can answer my question?
