Open Quick Look from protected web space directory with Model Viewer

Hi Community,

I am using Googles Model Viewer (https://modelviewer.dev/) to display 3D-models in the webbrowser. It also enables the user to open the 3D-models in AR-Applications. On iOS, Quick Look will be opened.

It all works fine and well, except when the web space directory is protected by HTTP Basic Auth (protection of the usdz-model-files is a requirement of my client).

As I understand it, Quick Look looses (or does not have any access to) the HTTP session, and therefore is not authenticated when trying to access the usdz-file on the protected web space directory.

The error message in Quick Look is: "Object requires a newer version of iOS".

Is there any way to open an usdz-file that is on a protected web space directory with Quick Look?
