Most effective way to get the methods of any collider object in Unity?

I have a bullet game object that detects enemies via OnTriggerEnter2D(). This was working perfectly until I added different enemy types:

private void OnTriggerEnter2D(Collider2D collision)
    {
        Enemy enemy = collision.GetComponent<Enemy>();
        if (enemy != null)
        {
            enemy.Destroy();
            GameObject effect_ = Instantiate(bulletEffect, transform.position, transform.rotation);
            Destroy(effect_, 0.5f);
            Destroy(gameObject);
        }
}

So simply if the bullet collides with Enemy() then it should call its Destroy() method.

The problem is that now I have added multiple enemies in my game, for example there is an enemy with the class name Runner() with its own death method.

I can add an if condition and cycle through every enemy type but that will become tedious after more enemies are added.

Whats the best way of doing this?

Thanks
