Script activate after a certain amount of time (CLOSED)

Beginner working on a unity school project and got stuck on how to write a code that would make a prefab gameobject duplicate itself one time after a certain amount of time. Tried to use
examples from Object.Instantiate but can't solve it. Help appreciated.

Code (CSharp):

1. using System.Collections.Generic;
2. using UnityEngine;
3.  
4. public class Gameplay : MonoBehaviour
5. {
6.  
7.     public GameObject coinOriginal;
8.     public GameObject coinContainer;
9.  
10.     void Start()
11.     {
12.         CreateCoins(1);
13.     }
14.  
15.     private void CreateCoins(int coinsNum)
16.     {
17.         for (int i = 0; i < coinsNum; i++)
18.         {
19.             // GameObject CoinClone = Instantiate(coinOriginal);
20.             GameObject CoinClone = Instantiate(coinOriginal, new Vector3(i * 0.6f, coinOriginal.transform.position.y, i * 0.75f), coinOriginal.transform.rotation);
21.             void Update()
22.     {
23.        
24.     }
25. }
26.     }
27. }
