Wrong GUI.AdvancedDynamicTexture.CreateFullScreenui documentation?

Bugs

https://github.com/fneitzel/babylonjs_gui_4.1_issue.git from codeSandbox above

import { AdvancedDynamicTexture } from "@babylonjs/gui";

let advancedTexture = AdvancedDynamicTexture.CreateFullscreenUI("test", true, scene);

This works.

But

import { AdvancedDynamicTexture } from "@babylonjs/gui";
let advancedTexture = AdvancedDynamicTexture.CreateFullscreenUI("test");

does not.

if I use:

import { AdvancedDynamicTexture } from "babylonjs-gui";
let advancedTexture = AdvancedDynamicTexture.CreateFullscreenUI("test");

it works.

Also rendering this:

optionswrapper.linkWithMesh(sphere);

just happens on rerender.

Thank you for your time!
