How do I add Player Health and Enemy Attacking to my game

Hello there, I have recently been trying to make a game but I need a way for my player to take damage. My enemy can currently follow the player and track its location but when it reaches the player, it cant attack but i can attack the enemy. If anyone has any scripts for player health and enemy attacking that would be great. ill post my playercombat script and my enemy script for if theres a way you can find to implement this into my scripts i already have

Player Combat Script

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class PlayerCombat : MonoBehaviour
 {
 
     //all variables
     public Animator animator;
     public Transform attackPoint;
     public float attackRange = 0.5f;
     public LayerMask enemyLayers;
     public int attackDamage = 20;
     public float attackRate = 1f;
     float nextAttackTime = 0f;
 
 
     // Update is called once per frame
     void Update()
     {
         // Attack
         
         if(Time.time >= nextAttackTime)
         {
             if (Input.GetButtonDown("Fire1"))
         {
             Attack();
             nextAttackTime = Time.time + 1f / attackRate;
         }
         }
         
     }
 
     void Attack()
     {
         //Play Attack Animation
 
         animator.SetTrigger("Attack");
 
         //Detect Enemies In Range Of Attack
 
         Collider2D[] hitEnemies = Physics2D.OverlapCircleAll(attackPoint.position, attackRange, enemyLayers);
 
         // Damage The Enemy
 
         foreach(Collider2D enemy in hitEnemies)
         {
             enemy.GetComponent<Enemy>().TakeDamage(attackDamage);
         }
     }
 
 
     void OnDrawGizmosSelected()
     {
         if(attackPoint == null)
             return;
 
         Gizmos.DrawWireSphere(attackPoint.position, attackRange);
     }
 }

Enemy Script

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Enemy : MonoBehaviour
 {
 
     //all variables
 
     public int maxHealth = 100;
     int currentHealth;
     public Animator animator;
     public GameObject AITracker;
     public string AIDestinationSetter;
 
     // Start is called before the first frame update
     void Start()
     {
         currentHealth = maxHealth;
     }
 
     public void TakeDamage(int damage)
     {
         
         // Enemy Taking Damage
         currentHealth -= damage;
 
         // Play Hurt Animation
 
         animator.SetTrigger("Hurt");
 
         if(currentHealth <= 0)
         {
             Die();
         }
     }
 
     void Die()
     {
         // Play Death Animation
 
         animator.SetBool("IsDead", true);
 
         // Disable The Enemy
 
         GetComponent<Collider2D>().enabled  = false;
         (AITracker.GetComponent(AIDestinationSetter) as MonoBehaviour).enabled = false;
         this.enabled = false;
     }
 }
 

any help would be greatly appreciated. Thank you in advance!
