How to actually use AuthenticationTokenProvider + ITokenCache in a own Auth Provider Definition? Is it similar or equal to cookies?

[DevTKSS]

uno.extensions/samples/Playground/Playground/AppHost.cs

Line 47 in 48d100b

.AddSingleton<IAuthenticationTokenProvider>(new SimpleAuthenticationToken { AccessToken = "My access token" })

found this in the playground and the implementation in the source, but nothing else.
How would this be used and where is it expected to get the AccessToken or RefreshToken from? I it working together with the CookieManager or the UseCookies(? but seems like only available on WebAssembly if I read the docs correctly...
Would need some AccessToken RefreshToken management also on e.g. Desktop...

https://platform.uno/docs/articles/features/working-with-cookies.html

seems like its used in the WebAuth Extensions
https://platform.uno/docs/articles/external/uno.extensions/doc/Learn/Authentication/HowTo-WebAuthentication.html

but thats not available on Desktop target - unoplatform/uno.templates#1665
Dont we have WebView on Desktop? 🤔

Found no real how to use cookies even in its own "how to" article here 🤔
https://platform.uno/docs/articles/external/uno.extensions/doc/Learn/Authentication/HowTo-Cookies.html
am I missing something? Dont we need to get it through any constructor - DI and use it somehow? If we need, and the above linked article "Working with Cookies" is not up to date, would be great if someone could tell me how to use that.

just from this lines here:

uno.extensions/src/Uno.Extensions.Authentication/HostBuilderExtensions.cs

Lines 125 to 150 in 48d100b

	public static IHostBuilder UseAuthentication(
	this IHostBuilder builder,
	Action<IAuthenticationBuilder> build,
	Action<IHandlerBuilder>? configureAuthorization = default)
	{
	var authBuilder = builder.AsBuilder<AuthenticationBuilder>();
	build?.Invoke(authBuilder);
	return builder
	.ConfigureServices((ctx, services) =>
	{
	if (ctx.IsRegistered(nameof(UseAuthentication)))
	{
	return;
	}
	services
	.AddSingleton<ITokenCache>(sp =>
	new TokenCache(
	sp.GetRequiredService<ILogger<TokenCache>>(),
	sp.GetRequiredDefaultInstance<IKeyValueStorage>()))
	.AddSingleton<IAuthenticationService, AuthenticationService>();
	})
	.Authorization(configureAuthorization);
	}

I would understand this as: "If you register e.g. webAuth customAuth or oidc, we will not attach Token handling" while those would be kind of essential, for all of them, or not?

I think my oAuth2 would need them so the user would not been asked again to Grant acces each time he starts his app...
