Can you check again something that is already in the IsTrigger collider ?

Okay so, I'm making a C4 planting system, and I'm in the last part where the C4 detects a destroyableWall, checks if it's time to destroy it, and if, destroys it.

The script works well, detects the wall and the other script finishes his work with timeToDestroyWall = true. The thing is, my C4 code won't work, and it' surely due to the fact that the checking is done only one time (it's not an Update() function and it's litteraly in the name, "OnTriggerEnter2D")

So, now you have a better understanding of my problem, here's the question :

What alternative can I use instead of OnTriggerEnter2D that would keeps checking items inside the collider ?

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class C4Manager : MonoBehaviour
 {
     public bool destroyableWall;
     public GameObject Inventory;
     public Inventory inventoryScript;
 
     public void Start()
     {
         Inventory inventoryScript = Inventory.GetComponent<Inventory>();
     }
 
     public void OnTriggerEnter2D(Collider2D other)
     {
         if(other.CompareTag("destroyableWall"))
         {
             destroyableWall = true;
 
             if (inventoryScript.timeToDestroyWall)
             {
                 Debug.Log("attempting destruction...");
                 Destroy(other);
             }
         }
     }
 }
