Show Admob interstitial in Game Over and Level Win

Hello!

I already have all the packages in my project of admob (with normal banner and interstitial), but i can´t put the interstitial showing after game over menu and level win menu..

I have the google mobile ads demo script, but i can´t make the ads appears in the end of the game...

Heres my gamemanager code:

Code (CSharp):

1. using System.Collections;
2. using UnityEngine.UI;
3.  
4.  
5. public class GameManager : MonoBehaviour {
6.     public int LevelNumber;

10.     public AudioClip audPickup;
11.     public AudioClip audWin;
12.     public AudioClip audCrash;
13.     //Panels
14.     public GameObject PausePanel;
15.     public GameObject PlayingPanel;
16.     public GameObject WinPanel;
17.     public GameObject LosePanel;
18.     public GameObject SettingsPanel;
19.     public Text txtGraphics;
20.     public Text MuteText;
21.  
22.     GameObject player;
23.  
24.     int StarsCollected;
25.     // Use this for initialization
26.     void Start () {
27.         player = GameObject.FindGameObjectWithTag("Player");
28.         Time.timeScale = 1;
29.         StarsCollected = 0;
30.  
31.  
32.         //Gets whether the sound is set to muted, and changes audio settings accordingly.
33.         if (PlayerPrefs.GetInt("SoundSettings") == 1)
34.         {
35.             AudioListener.pause = false;
