ML Agent Moving But Not Rotating

hi, so I followed this tutorial by code monkey: https://www.youtube.com/watch?v=zPFU30tbyKs&t=2419s but the problem is that the agent doesn't rotate when he moves can any one help? here's the code:

 public override void OnActionReceived(ActionBuffers actions)
     {
         float moveX = actions.ContinuousActions[0];
         float moveZ = actions.ContinuousActions[1];
 
         float moveSpeed = 3;
 
 
         transform.localPosition += new Vector3(moveX, 0, moveZ) * Time.deltaTime * moveSpeed;
         
     }

so is there a way I can rotate the agent using the moveX and moveZ? I already tried this:

 transform.LookAt(new Vector3(moveX, 0, moveZ));
