how do i damage the player on enemy start, Not collision

Question

so i have this basic enemy script that works fine

public class Enemy : MonoBehaviour { public float health; public float damage;

 public GameObject deatheffect;

public void Update() {

     if (health <= 0) 
     { 
         Instantiate(deatheffect,transform.position,transform.rotation);
         Destroy(gameObject);
     }

 }

 void OnTriggerEnter(Collider hitInfo)
 {
   
         Player player = hitInfo.GetComponent<Player>();
         if (player != null)
         {
         player.health -= damage;
         health -= player.attackPower;
         }

 }

}

but i have a boss that instantiates an object for a health debuff and i dont want the debuff to use collision. i just want the player to lose health on the debuffs Start.

so how do i change the OnTriggerEnter to Start.ive tried this

public class testfox : MonoBehaviour {

 public float attackBuff;
 public float damage = 4;
 public GameObject player;


 void Start()
 {
    player = GameObject.Find("Player");
    player.health -= damage;
    Destroy(gameObject);
 }

},

  public float attackBuff;
  public float damage = 4;
  public PlayerScript player;  //Declare variable for the players script
  void Start()
  {
     player = GameObject.Find("Player").GetComponent<PlayerScript>();  //Find the player and get it's script component
     player.health -= damage;  //Provided health is defined for the player this should do it
     Destroy(gameObject);
  }

I would suggest to get player reference using built-in player tag. It will be less costly.

 player = GameObject.FindObjectWithTag("Player").GetComponent<PlayerScript>();

// PlayerScript

 public class PlayerController : MonoBehaviour{
 
 int health = 100;
    
  public void TaskDamage(int damage) {
         health -= damage;
         if (health <= 0) {
         // GameOver Screen
         }
     }
 }

Enemy Script

  public class EnemyAI : MonoBehaviour{
         
         int AttackDamage = 10;
         private PlayerController playerScript; // <-- the player script
     
       private void Awake() {
             playerScript = GameObject.Find("Player").GetComponent<PlayerController>();
     // The PlayerController script must be on the Game Object Player
         }
     
            private void Start() {
              AttackPlayer(AttackDamage);
             }
         
         private void AttackPlayer(int damage){
         playerScript.TaskDamage(damage)
              }
         }
