Loading extension from a URL that requires authentication is not working

Related to #1648
I am trying to host the extensions and use custom_extension_repository property to point to my service.. the extensions will be behind a proxy that will check for cookies to only allow authenticated requests and the requests to load the extensions are therefore failing. (Notice that the request is going to a different domain that is configured to accept CORS requests for the domain running duckdb-was m so the issue I believe is not with CORS headers)

In a code that I control, I fixed a similar issue before by adding

credentials: 'include',

to the fetch request..

Is there a way to do the same with loading the extensions?
Thanks!
