How to stretch a cylinder when dragging with a Ray Interactor?

Question

I'm making a VR game in Unity.

I want to select a cylinder with ray interactor and drag it, and as I drag, it should stretch.

This is the code I have currently for 2D:

[RequireComponent(typeof(Collider))]

public class ScaleWithDrag : MonoBehaviour
{
    public Transform WorldAnchor;
    private Camera mainCamera; //stores the reference of the camera
    private float CameraZDistance; //move the object
    private Vector3 InitialScale; //hold the inital scale of the gameobject

    void Start()
    {
        InitialScale = transform.localScale;
        mainCamera = Camera.main;
        CameraZDistance = mainCamera.WorldToScreenPoint(transform.position).z;
    }
    private void OnMouseDrag()
    {
        Vector3 MouseScreenPosition = new Vector3(Input.mousePosition.x, Input.mousePosition.y, CameraZDistance); //z axis added to screen point
        Vector3 MouseWorldPosition = mainCamera.ScreenToWorldPoint(MouseScreenPosition); //screen point conversted into world point

        // change transform
        float Distance = Vector3.Distance(WorldAnchor.position, MouseWorldPosition);//change scale
        transform.localScale = new Vector3(InitialScale.x, Distance/2f, InitialScale.z);// /2 for cylinder

        Vector3 middlePoint = (WorldAnchor.position + MouseWorldPosition) / 2f;
        transform.position = middlePoint;

        //adjjust the rotation of the game object
        Vector3 rotationDirection = (MouseWorldPosition - WorldAnchor.position); //change rotation
        transform.up = rotationDirection;
    }
}
