How Can i Make Fps Controller Rotate and face a target.

Hey guys I'm developing my first game so am a bit new to Unity, so my problem is am trying to rotate the Fps Controller to face a target by the push of a button. I managed to rotate the camera alone by attaching this code to it but only the camera rotates so it completely messes up the walking.

 public class PlayerRotate : MonoBehaviour {
 
     public Transform target;
 
     void Update(){
         if(Input.GetKeyDown("r")){
             print ("Rotate");
             transform.LookAt(target.position);
 
     }
 }
 
 }

I also tried attaching the same script to the Fps Controller but nothing happens. Anyone's help would be greatly appreciated, Thanks
