what to do to get the explosion animation of an object

what to do to get the explosion animation of an object
I would like the elements that are in the scene after winning a round to disappear with the explosion animation.
this is the script for the whole game:

using System.Collections;
using UnityEngine;
using UnityEngine.SceneManagement;


[RequireComponent(typeof(GameUI))]
public class GameController : MonoBehaviour
{

 
    public static GameController Instance { get; private set; }

    [SerializeField]
    private int knifeCount;

    [Header("Knife Spawning")]
    [SerializeField]
    private Vector2 knifeSpawnPosition;
    [SerializeField]
    
    private GameObject knifeObject;

    
    public GameUI GameUI { get; private set; }

    private void Awake()
    {
        
        Instance = this;

        GameUI = GetComponent<GameUI>();
    }

    private void Start()
    {
        
        GameUI.SetInitialDisplayedKnifeCount(knifeCount);
        
        SpawnKnife();
    }

    
    public void OnSuccessfulKnifeHit()
    {
        if (knifeCount > 0)
        {
            SpawnKnife();
        }
        else
        {
            StartGameOverSequence(true);
        }
    }

    
    private void SpawnKnife()
    {
        knifeCount--;
        Instantiate(knifeObject, knifeSpawnPosition, Quaternion.identity);
    }

   
    public void StartGameOverSequence(bool win)
    {
        StartCoroutine("GameOverSequenceCoroutine", win);
    }

    public AudioClip impact6;
    private IEnumerator GameOverSequenceCoroutine(bool win)
    {
        if (win)
        {
            AudioSource.PlayClipAtPoint(impact6, transform.position);
            yield return new WaitForSecondsRealtime(0.3f);
            FindObjectOfType<LevelLoader>().LoadNextLevel();
            FindObjectOfType<SaveScene>().Load_Saved_Scene();
            
        }
        else 
        {
            GameUI.ShowRestartButton();
        }
    }
    
    public void RestartGame()
    {
        
        SceneManager.LoadScene(PlayerPrefs.GetInt("SavedScene"));
    }
}

if anyone needs a script for object data, I can also provide it

What explosion animation do you mean? Is it one you have made yourself?
There is no built-in explosion animation in unity, so either you have to get one online or from the asset store and import it into your project, then trigger the animation when the level ends.
