blazor.net with HttpClient sending credentials

I have an api hosted on IIS that I am trying to call through a Blazor.Net client app with the HttpClient as provided in the example.

Since the api endpoint is hosted on IIS with windows authentication, I need to include credentials when the call is made.

I tried to create an instance of the httpClient instead of using the static method provided in the examples but I receive the PlatformNotSupported exception.

Is there a way to pass credentials with the Static HttpClient as used in Blazor.net?

If I use JavaScript interop with XMLHttpRequest and set withCredentials to true, the api returns data. However I would rather not use js to get the data but rather C#.

Thanks,
