Third person Camera With Lerp trouble

Hey,

I've got a script for a camera that follows and orbits around a target using the mouse control but I also want it to have a smooth follow component as well so that the camera follows and catches up to the target as it moves around. Ive tried implementing Lerp but I haven't had any success. I'm very new to Unity so any help would be very much appreciated.

     public bool lockCursor;
     public float mouseSensitivity = 10;
     public Transform target;
     public float dstFromTarget = 10;
     public Vector2 pitchMinMax = new Vector2 (-40, 85);
 
 
     public float rotationSmoothTime = .12f;
     Vector3 rotationSmoothVelocity;
     Vector3 currentRotation;
 
 
 
     float yaw;
     float pitch;
 
     void Start() {
         if (lockCursor) {
             Cursor.lockState = CursorLockMode.Locked;
             Cursor.visible = false;
         }
 
 
 
     }
         
     void LateUpdate () {
 
 
         yaw += Input.GetAxis ("Mouse X") * mouseSensitivity;
         pitch -= Input.GetAxis ("Mouse Y") * mouseSensitivity;
         pitch = Mathf.Clamp (pitch, pitchMinMax.x, pitchMinMax.y);
     
         currentRotation = Vector3.SmoothDamp (currentRotation, new Vector3 (pitch, yaw), ref rotationSmoothVelocity, rotationSmoothTime); 
         transform.eulerAngles = currentRotation; 
 
     
         transform.position = target.position - transform.forward * dstFromTarget;
 
     }
 }

Thank you.
