Instantiate Prefab From Script Inside A Canvas

Hello Im making brick breaker game. I want to load level2 prefab inside a canvas. I found in forum but i can't use to this function in to my code because i didnt use gameobject im using Transform. Please Help :)

Old Forum Code:

  GameObject enemy = Instantiate(enemyPrefab, new Vector3(0, 0, 0), Quaternion.identity) as GameObject;
  enemy.transform.SetParent (GameObject.FindGameObjectWithTag("Canvas").transform, false);

MyCode:

 public int numberOfBricks;
 public Transform[] Levels;
 public int currentLevelIndex = 0;
 
 public void UpdateNumberOfBricks()  
     {
         numberOfBricks--;
         if(numberOfBricks <= 0)
         
             if (currentLevelIndex >= Levels.Length - 1) 
             {
                 GameOver(); 
             }
             else
             {
                 gameOver = true;
                 Invoke("LoadLevel", 3f); 
             }
     }
 void LoadLevel()
     {
          currentLevelIndex++;
          Instantiate(Levels[currentLevelIndex], Vector2.zero, Quaternion.identity);
          numberOfBricks = GameObject.FindGameObjectsWithTag("brick").Length;
         gameOver = false;
     }

Thanks
