Making an object orbit using c# script for Unity+Vuforia

Question

I have written a simple c# script for Unity+Vuforia. I want to create a simple sample project where an object like a sphere is revolving (orbiting) origin (0,0,0) above image target.

The code I have written is here

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Vuforia;

public class Orbit : MonoBehaviour
{
    float angles;
    float radiuss;
    float angleSpeed;

    // Start is called before the first frame update
    void Start()
    {
        angles = 0;
        radiuss = 0.2f;
        angleSpeed = 1;

    }

    // Update is called once per frame
    void Update()
    {
        angles += Time.deltaTime * angleSpeed;


        float x = radiuss * Mathf.Cos(Mathf.Deg2Rad * angles);
        float z = radiuss * Mathf.Sin(Mathf.Deg2Rad * angles);
        float y = 0;

        transform.position = new Vector3(x, y, z);
    }
}

It works perfectly fine if I am not using it with Vuforia, but when I attach this script as component to an object in Vuforia, it does not work and acts weird. These are the configurations and hierarchy

Please help me out, I tried a lot of things.

It looks to me like you want to change this line:

transform.position = new Vector3(x, y, z);

to use localPosition instead:

transform.localPosition = new Vector3(x, y, z);

This says "place me here relative to my parent's coordinate system," so as Vuforia moves the parent around, this object will track that motion, while also layering its own motion on top.
