how to enable is trigger on a 2d box collider for a certain amount of time ?

Heya…
I wanna disable a 2D box collider for a certain amount of time… let’s say 3 seconds, after those three seconds I would like it to enable itself again automatically.
the only way I can wrap my head around this is by using triggers,
and like setting it to true or false after a certain amount of time.
how would I be able to do this?

Oh and other ways of doing something like this is totally welcome!,

BoxCollider2D boxCollider2D;
public float time = 3f;

    private void Awake()
    {
        StartCoroutine(Example());
    }

    IEnumerator Example()
    {
        boxCollider2D.isTrigger = true;
        yield return new WaitForSeconds(time);
        boxCollider2D.isTrigger = false;
    }

just wanna share this other method of doing cooldown related stuff since you mention you’re interested in alternate answers – this potentially lets you rapidly reset the time toward re-enabling the collider without having to cancel out the coroutine, which can be a pain depending on what youre doing with it. this version is good for snappy attack interactions and the like.

            BoxCollider2D collider;
    	float enabletime;
    	float cooldown = 3f; //or whatever amount of time you want the colldier off for.
    
    	bool collideroff;
    
    	// call this function whenever you want to turn the collider off.
    	void TurnOffCollider()
    	{
    		collider.isTrigger = false;
    		collideroff = true;
    		enabletime = Time.time + cooldown;
    	}
    	void Update()
    	{
    		if(collideroff && Time.time > enabletime)
    		{
    			collider.isTrigger = true;
    			collideroff = false;
    		}
    	}
