How to call function (or corutine) like update if button pressed

How to call function (or corutine) like update func. if button pressed.
I have corutine and start corutine from function. How in new input system call function like Update if i pressed ctrl button?

I make Action (look screen.) But i don't know how it use.

Code (CSharp):

1. bool reload = false;
2.  
3. IEnumerator Shoot()
4.     {
5.         reload = true;
6.         GameObject BulletG =  Instantiate(Bullet,SpawnPoint);
7.  
8.         yield return new WaitForSeconds(1f);
9.         reload = false;
10.     }
11.  
12.  
13. public void StartShoot()
14.     {
15.         if (reload == false)
16.         {
17.             StartCoroutine(Shoot());
18.         }
19.     }

 

On a simple: I want hold the CTRL and call every frame function StartShoot();

 

is this what you need?

YourInputClassName.YourActionsMap.YourAction.performed += context => StartShoot();
