How to include credentials when making CORS requests from Blazor?

On a blazor client application, what is the equivalent of jQuery ajax WithCredentials or JavaScript credentials: 'include'?

With Javascript I am able to say:

fetch('https://www.example.com/api/test', {   credentials: 'include'});

which includes auth cookie while making request and server responds with 200. I am trying to write same with Blazor using HttpClient.
