Destroy UI image and text after onmousedown

Hi all. I have made a script so when the player does a mouse click a UI image and text pops up. I have attached this script to 100 gameobjects (a different image for each one, the same text for all). What I want to do know is to destroy-disable the UI after viewing the UI once. So if I click on gameobject 1, the UI image and text appears but if I want to view this twice then nothing happens. I used destroy function but it destroys all UI images and texts and if I click on game object 1 then gameobject 2-100 do not seem to have anything. Any help?

 using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  using UnityEngine.UI;
 
 public class RandomIndi : MonoBehaviour {
 
     public GameObject textprefab;
     public GameObject imageprefab;
 
     IEnumerator OnMouseDown()
     {
         textprefab.SetActive (true);
         imageprefab.SetActive (true);
 
         Time.timeScale = 0.0f;
         yield return new WaitForSecondsRealtime(3.5f);
 
 
         Destroy (textprefab);
         Destroy (imageprefab);
         /*textprefab.SetActive (false);
         imageprefab.SetActive (false);*/
 
         Time.timeScale = 1.0f;
 
     }
 }
