Making a recurring IEnum with Update-like behaviour for Unity

IEnumCircularTest.cs

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

public class IEnumTest : MonoBehaviour
{
    public bool isTracking = false;

    // Trigger to start, can be whatever
    void Start()
    {
        StartCoroutine(DebugTracking());
    }

    // Trigger to stop
    private void OnDestroy()
    {
        StopAllCoroutines();
    }

    IEnumerator DebugTracking()
    {
        if (!isTracking)
        {
            Debug.Log("I'm false");
            yield return new WaitForEndOfFrame(); // IMPORTANT otherwise it will start a loop of death

        }

        if (isTracking)
        {
            Debug.Log("I'm true");
            yield return new WaitForEndOfFrame(); // IMPORTANT otherwise it will start a loop of death

        }
        
        // Circular reference to keep updating
        StartCoroutine(DebugTracking());

    }
