Im looking for this trigger to only work once, the first time. I managed to transcript this and found some alternatives to add the function either by destroying the collider or limiting its function, but i lack the c# knowledge to add on it. If anyone knows, it would be every helpful!

You can limit it with a boolean variable:

private bool isFirstCall = true;

void OnTriggerEnter2D(Collider2D col)
{
    if (isFirstCall)
    {
        isFirstCall = false;

        // next, your logic
    }
}

Destroying and Instantiating during Runtime is not a best Practice to use Unity due to performance issues. Instead of Destroying, you can disable the target component.
