How i make the NPC friend stop following me and start to follow the enemy when he is near???!!!

I am developing a game based on Solo Leveling, and my compannion ("shadows") is following me and i cannot find a way to make them start to follow the enemy when he is near. Does anyone knows how to solve my problem?

Here is the code:

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class ShadowFollow : MonoBehaviour {

 public Transform target;
 public int moveSpeed = 5;
 public int rotationSpeed = 2;
 public Transform myTransform;
 public float minDistance = 7f;
 public float maxDistance = 15f;

 void Awake()
 {
     myTransform = transform;
 }

 void Start()
 {
     
     target = GameObject.FindWithTag("Player").transform;
     
 }

 void Update()
 {
     Vector3 Distance = target.position - myTransform.position;
     if (Distance.sqrMagnitude > minDistance * minDistance)
     {
         myTransform.rotation = Quaternion.Slerp(myTransform.rotation, Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed * moveSpeed * Time.deltaTime);
         myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
     }
 }

}
