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

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(); //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);
}

// 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)
             }
        }
