How to Make Game Object (Enemy) Move (Right to Left) in 2D Endless Runner Game?

Hello right now i'm making 2d endless runner game when the player move to the right automatically, so i do have code that will does object pooling and generate at the generation point of the enemy, but it won't move to the left. The object doesn't have RigidBody2D, and i don't have idea to implement this code to mine correctly.

EnemyPool.GetPooledObject= transform.Translate(Vector3.left * Time.deltaTime, Camera.main.transform);

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class KayuPlatformGenerator : MonoBehaviour {
 
     public GameObject thePlatform;
     public Transform generationPoint;
     private float distanceBetween;
     private float platformWidth;
     public float distanceBetweenMin;
     public float distanceBetweenMax;
     public float randomEnemyThreshold;
     public ObjectPooler enemyPool;
     public ObjectPooler theObjectPool;
 
     void Start () {
         platformWidth = thePlatform.GetComponent<BoxCollider2D>().size.x;
     }
 
     void Update () {
         if (transform.position.x < generationPoint.position.x) {
             distanceBetween = Random.Range (distanceBetweenMin, distanceBetweenMax);
             transform.position = new Vector3 (transform.position.x + (platformWidth / 2) + distanceBetween, transform.position.y, transform.position.z);
             GameObject newPlatform = theObjectPool.GetPooledObject ();
             newPlatform.transform.position = transform.position;
             newPlatform.transform.rotation = transform.rotation;
             newPlatform.SetActive (true);
 
             if (Random.Range (0f, 100f) < randomEnemyThreshold) 
             {
                 GameObject newEnemy = enemyPool.GetPooledObject ();
                 float enemyXPosition = Random.Range (-platformWidth / 2+8f, platformWidth / 2-8f);
                 Vector3 enemyPosition = new Vector3 (mbakEnemyXPosition, Random.Range(9f, 11f), 0f);
                 newMbakEnemy.transform.position = transform.position + mbakEnemyPosition;
                 newEnemy.transform.rotation = transform.rotation;
                 newEnemy.SetActive (true);
             }
             transform.position = new Vector3 (transform.position.x + (platformWidth / 2), transform.position.y, transform.position.z);
         }
     }
 }
