Show Admob interstitial in Game Over and Level Win

Unity Engine
1

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:

using System.Collections;
using UnityEngine.UI;


public class GameManager : MonoBehaviour {
    public int LevelNumber;
    public GameObject imgStar1;
    public GameObject imgStar2;
    public GameObject imgStar3;
    public AudioClip audPickup;
    public AudioClip audWin;
    public AudioClip audCrash;
    //Panels
    public GameObject PausePanel;
    public GameObject PlayingPanel;
    public GameObject WinPanel;
    public GameObject LosePanel;
    public GameObject SettingsPanel;
    public Text txtGraphics;
    public Text MuteText;

    GameObject player;

    int StarsCollected;
    // Use this for initialization
    void Start () {
        player = GameObject.FindGameObjectWithTag("Player");
        Time.timeScale = 1;
        StarsCollected = 0;


        //Gets whether the sound is set to muted, and changes audio settings accordingly.
        if (PlayerPrefs.GetInt("SoundSettings") == 1)
        {
            AudioListener.pause = false;
            MuteText.text = "";
        } else if (PlayerPrefs.GetInt ("SoundSettings") == 0)
        {
            AudioListener.pause = true;
            MuteText.text = "/";
        }

        txtGraphics.text = GetQualityName (QualitySettings.GetQualityLevel());
    }



public    void CollectStar ()
    {
        audio.PlayOneShot (audPickup);
        StarsCollected += 1;

        if (StarsCollected == 1)
            imgStar1.SetActive (true);
        if (StarsCollected == 2)
            imgStar2.SetActive (true);
        if (StarsCollected == 3)
            imgStar3.SetActive (true);

    }

    public void CollectTime()
    {
        audio.PlayOneShot (audPickup);
    }

    {

        Time.timeScale = 0;
        int tempStars = PlayerPrefs.GetInt ("Level" + LevelNumber.ToString () + "Stars");
        audio.PlayOneShot (audWin);
        if (tempStars < StarsCollected)
        {
            PlayerPrefs.SetInt ("Level" + LevelNumber.ToString () + "Stars", StarsCollected);
        }

        PausePanel.SetActive (false);
        PlayingPanel.SetActive (false);
        WinPanel.SetActive (true);
        LosePanel.SetActive (false);
        SettingsPanel.SetActive (false);

        }


public    void LevelLose()
    {
        player.audio.Stop();
        audio.PlayOneShot (audCrash);
