OnTriggerEnter launching a delayed tween

I am trying to set up the following: a box collider that serves as a trigger, which when the player enters triggers a tween path after a further preset delay. The code I have below starts the code regardless of whether the player has entered the trigger or not, i.e. as soon as you enter Play Mode, the delay countdown begins. Any help would be hugely appreciated - I've tried formatting things around every way I can think of, and this is the closest I've come:

 using UnityEngine;
 using System.Collections;
 using DG.Tweening;
 
 public class Move : MonoBehaviour 
 {
     public int laps = 1;
     public float speed = 10f;
     public int delay = 1;
     public Transform target;
     public PathType pathType = PathType.Linear;
     public Vector3[] waypoints = new[] 
     {
         new Vector3 (0, 0, 0),
         new Vector3 (5, 0, 0),
         new Vector3 (5, 0, 5),
         new Vector3 (0, 0, 5)
     };
 
     void OnTriggerEnter()
     {
         StartCoroutine ("wait");
 
     }
 
     IEnumerator Start()
     {
         {
             yield return new WaitForSeconds (delay);
             StopCoroutine ("wait");
         }
         
         Tween t = target.DOPath (waypoints, speed, pathType)
             .SetOptions (true)
             .SetLookAt (0.001f);
         
         t.SetEase (Ease.Linear).SetLoops (laps);
     }
 }
