Autodesk Viewer Proxy with streamingV2

Autodesk recommends in general to use a Proxy for the Viewer, especially for additional authorization.

What would be the recommended way to use it along the streamingV2 Feature, since without it the models take much more time to load?

Following the tutorial in aps.autodesk.com/blog/proxying-aps-viewer for NodeJS I see that the browser opens multiple websocket connections and sends some initial messages but no response is send and instead the websocket is closed resulting in slow page load.

Also the Bearer token is send without a proxy through the initial websocket message and this field is empty if a proxy is used and since the proxy just uses the initial http handshake it doesn’t overwrite the websocket payload itself
