Is it possible to load an image as a texture with the WebRequest?

[ProtoArts]

I'm trying to change the texture of an object using an image from the Internet, using the UnityWebRequestTexture API.
The scene works perfectly in the editor, but when I try it in the sandbox online, the code cannot recognize the method for the WebRequestTexture.

When I check the code in VS it says "RS0030 The symbol has been flagged for possible banning in this project; please contact Spatial if you would like to continue using this API."

Here is the code:

using System.Collections;
using UnityEngine;
using UnityEngine.Networking;

public class WebRequestImage : MonoBehaviour
{
    [SerializeField] private MeshRenderer Screen;
    [SerializeField] private string ImageLink;

    public void Interact() //interaction input
    {
        Debug.Log("Input recived...");
        StartCoroutine(LoadImage(ImageLink));
    }

    IEnumerator LoadImage(string link)
    {
        UnityWebRequest request = UnityWebRequestTexture.GetTexture(link);
        yield return request.SendWebRequest();

        if (request.result != UnityWebRequest.Result.Success)
        {
            Debug.Log(request.error);
        }
        else
        {
            Screen.material.SetTexture("_ImageTexture", DownloadHandlerTexture.GetContent(request));
            Debug.Log("Image Loaded");
        }

    }
}

Do you know if this API is experimental for Spatial?
