What is the right way to use get key down in this scenario?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System;

public class Q : MonoBehaviour
{

    void OnTriggerStay2D(Collider2D collision)
    {        
        if (Input.GetKeyDown("q"))
        {
            Destroy(collision.gameObject);

        }
    }
}

ok so i wrote code that is supposed to detect when another object is colliding with it to allow the player to press a key to destroy the collider. the code is able to detect a collider but is not able to detect a key press while the collider is being detected. I have zero clue to as why this is happening so if anybody can help that would be great thank you

If you look at the documentation for GetKeyDown, you'll see that it needs to be in your Update callback. This would be super easy to fix though!

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System;

public class Q : MonoBehaviour
{
    bool _qPressed;

    void Update()
    {
        _qPressed = Input.GetkeyDown("q");
    }


    void OnTriggerStay2D(Collider2D collision)
    {        
        if (_qPressed)
        {
            Destroy(collision.gameObject);

        }
    }
}
