Question Enable/Disable Input

Hi all

I'm trying to figure out how to enable and disable the input system temporarily. I want to future-proof avoiding players potentially spamming an input that interrupts a coroutine that causes a glitch that makes it so that coroutine stops running. I think I have most of it figured out, but I don't think I'm using the right language or I'm doing something wrong. Any help would be appreciated.
It's also been a while since I've embedded code in the Unity forums so I hope I do this right.

Code (csharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.InputSystem;
6.  
7. public class ADSMakarov : MonoBehaviour
8. {
9.  
10.     public GameObject Gun;
11.     public GameObject ADSGun;
12.     public static bool isAiming = false;
13.     public PlayerInput input = new PlayerInput();
14.  
15.     // Start is called before the first frame update
16.     void Start()
17.     {
18.     }
19.  
20.     // Update is called once per frame
21.     void Update()
22.     {
23.         if(Input.GetMouseButtonDown(1))
24.         {
25.             isAiming = true;
26.             StartCoroutine(ADSPistol());
27.             Gun.GetComponent<Animation>().Play("MakarovADS");
28.         }
29.  
30.         if(Input.GetMouseButtonUp(1))
31.         {
32.             isAiming = false;
33.             StartCoroutine(ADSPistol2());
34.         }
35.     }
36.  
37.     IEnumerator ADSPistol()
38.     {
39.         yield return new WaitForSeconds(.3f);
40.         ADSGun.SetActive(true);
41.         Gun.SetActive(false);
42.     }
43.  
44.     IEnumerator ADSPistol2()
45.     {
46.             input.disable();
47.             yield return new WaitForSeconds (.75f);
48.             Gun.SetActive(true);
49.             Gun.GetComponent<Animation>().Play("MakarovADS2");
50.             StopCoroutine(ADSPistol());
51.             ADSGun.SetActive(false);
52.             input.enable();
53.     }
54. }
