Question How to disable button on on click?

I want to show image using OnMouseDown on a game object in the scene. I wrote the script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class ImageClick : MonoBehaviour
7. {
8.     [SerializeField]
9.     public Image image;
10.     public Button closingButton;
11.  
12.     // Start is called before the first frame update
13.     void Start()
14.     {
15.         image.enabled = false;
16.         closingButton.enabled = false;
17.     }
18.  
19.     // Update is called once per frame
20.     void OnMouseDown()
21.     {
22.  
23.         image.enabled = !image.enabled;
24.         closingButton.enabled = !closingButton.enabled;
25.     }
26.  
27.     void Update()
28.     {
29.         if (Input.GetMouseButtonDown(1) || Input.GetKeyDown(KeyCode.Escape)) //closing image on RMB click or on ESC key press
30.         {
31.             image.enabled = false;
32.             closingButton.enabled = false;
33.         }
34.        
35.     }
36.  
37. }
38.  

which I attach to the game object in the scene. I also added the Button which is meant to appear with the appearance of image and disappear on click. I tried using the OnClick method in the Button's Inspector pane:

but it does not work correctly: the button appears on start, closes the image, but does not disables itself after click.
What can be done to make it work like intended?
Thank you in advance

 

Okay, i fixed it. Maybe not the best way to fix it, but it works.
Here's the new script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class ImageClick : MonoBehaviour
7. {
8.     [SerializeField]
9.     public Image image;
10.     public GameObject closingButton;
11.  
12.     // Start is called before the first frame update
13.     void Start()
14.     {
15.         image.enabled = false;
16.         closingButton.SetActive(false);
17.     }
18.  
19.     // Update is called once per frame
20.     void OnMouseDown()
21.     {
22.  
23.         image.enabled = !image.enabled;
24.         closingButton.SetActive(true);
25.     }
26.  
27.     void Update()
28.     {
29.         if (Input.GetMouseButtonDown(1) || Input.GetKeyDown(KeyCode.Escape)) //closing image on RMB click or on ESC key press
30.         {
31.             image.enabled = false;
32.             closingButton.SetActive(false);
33.         }
34.      
35.     }

And OnClick for the button on the Inspector pane I selected GameObject.SetActive for the button
