WebAuthenticationBrokerProvider for Desktop?

[Mike-E-angelo]

I am viewing this page:
https://platform.uno/docs/articles/features/web-authentication-broker.html

All platforms are listed with the exception of desktop. I am using this as my default platform for development and when I attempt to use the built-in/generated Open Connect ID authentication scenario/feature in a basic project, I get the following exception thrown during login via IdentityModel.OidcClient.OidcClient.LoginAsync:

System.NotImplementedException: The method or operation is not implemented.
   at Uno.AuthenticationBroker.WebAuthenticationBrokerProvider.AuthenticateAsyncCore(WebAuthenticationOptions options, Uri requestUri, Uri callbackUri, CancellationToken ct) in /__w/1/s/src/Uno.UWP/Security/Authentication/Web/WebAuthenticationBrokerProvider.skia.cs:line 23

   at Uno.Extensions.Authentication.Oidc.WebAuthenticatorBrowser.InvokeAsync(BrowserOptions options, CancellationToken cancellationToken)

I am curious if I am overlooking something obvious. Searching resulted in the above page and nothing else substantial.

Thank you for any assistance you can provide. 🙏👍

Indeed the API is not currently supported on Desktop, created issue #19143

As an alternative it should be possible to implement the authentication flow using external browser (using API like Launcher). Unfortunately, I don't have a specific example at hand right now
