Add moving stuff as child with Z offset which will be distance from headset. Use this to rotate the root gameobject.

MoveItemToView.cs

using DG.Tweening;
using Sirenix.OdinInspector;
using UnityEngine;

public class MoveItemToView : MonoBehaviour
{

    [Header("Found dynamically.")]
    public Transform headsetTransform;
    
    public GameObject itemParent;

    private void Start ()
	{
		DOTween.Sequence()
			.SetDelay(0.1f)
			.AppendCallback(() =>
			{
				if (itemParent)
				{
					itemParent = gameObject;
				}
				headsetTransform = VRTK.VRTK_DeviceFinder.HeadsetTransform();
				itemParent.transform.position = headsetTransform.position;
			})
			.Play();
	}

	void Update ()
	{
        if (headsetTransform == null)
            return;

	    var newAngle = Quaternion.LerpUnclamped(itemParent.transform.rotation,
	        headsetTransform.rotation, Time.deltaTime);
	    itemParent.transform.rotation = newAngle;
        
	}
}
