I want to add a health bar to existing code

I already have code that handles the enemy's health what I want to do is incorporate a health bar system that would be managed by the current code. If anyone could please help me with this I would really appreciate it I've checked all the other related topics to this issue but all I see is separate code that would be on there own, what I need is something that is used within my current code.

Please someone help.

Here is my code:

using UnityEngine; using System.Collections;

public class DamagableObject : MonoBehaviour {

 public bool m_Invincible = false;
 public float m_MaxHealth = 100f;
 
 [SerializeField]
 public float m_Health = 100f;
 
 public DecayingObject m_DeathEffectPrefab;
 public DecayingObject m_RemainsPrefab;
 public string m_DeathAnimation;
 
 /*public virtual float health
 {
     set
     {
         if (!m_Invincible ||  m_Health < value)
         {
             m_Health = value;
         }
         if (m_Health <= 0)
         {
             Death();
         }
         else if (m_Health > m_MaxHealth)
         {
             m_Health = m_MaxHealth;
         }
     }
     
     get
     {
         return m_Health;
     }
 }*/
 
 public virtual void DealDamage(float val, Vector3 pos, Vector3 normal)
 {
     if (val > 0f && !m_Invincible)
     {
         m_Health -= val;
         if (m_Health <= 0)
         {
             Death();
         }
     }
 }
 
 public virtual void Heal(float val)
 {
     if (val > 0f)
     {
         m_Health += val;
         if (m_Health > m_MaxHealth)
         {
             m_Health = m_MaxHealth;
         }
     }
 }
 
 public float GetHealth()
 {
     return m_Health;
 }

     bool error = false;

         error = true;
     }

     {
         Debug.LogError("Invalid health range expected 0-" + m_MaxHealth + " got " + m_Health);
         error = true;
     }
     if (error)
     {
         Debug.Break();
     }
 }    
 
 
 
 protected void Death()
 {
     if (m_DeathEffectPrefab != null)
     {
         Instantiate(m_DeathEffectPrefab, transform.position, transform.rotation);
     }
     if (animation != null && animation[m_DeathAnimation] != null)
     {
         animation.CrossFade(m_DeathAnimation, 0.5f, PlayMode.StopAll);
         if (m_RemainsPrefab != null)
         {
             StartCoroutine("WaitForDeathAnimation", animation[m_DeathAnimation].length);

         }
         Destroy(gameObject);
     }
 }
 
 protected IEnumerator WaitForDeathAnimation(float time)
 {
     yield return new WaitForSeconds(time);

     Destroy(gameObject);
