Adjusting OnTriggerEnter2D() for OnParticleTrigger()

I have the following code for a damage script on bullets:

 void OnTriggerEnter2D (Collider2D hitInfo)
 
     {
     
             enemy enemy =  hitInfo.GetComponent<enemy>();
      
             if (enemy!= null)
             {
                 enemy.TakeDamage(damage);
                 Destroy(gameObject);
     
             }
     }

I'm trying to code a new weapon that uses particles instead of bullet prefabs, and the OnParticleTrigger function cannot have parameters, so this code won't work as-is. When I try, I get thrown this:

Script error: OnParticleTrigger

The message may not have any parameters.

What can I change or rewrite to get this to work?
