Strongly typed IDs

[DirtyNative]

I am wondering how to get strongly typed IDs to work with Refit. I am using this package to automatically generate all needed things for the IDs. Here are the classes:

[StronglyTypedId(typeof(Guid))]
public partial struct UserId
{
	public partial class UserIdTypeConverter { }
	public partial class UserIdJsonConverter { }
	public partial class UserIdNewtonsoftJsonConverter { }
}

public interface IAudioSourceRefitClient
{
	[Get($"{Routes.AudioSourceRoutes.BaseRoute}/{Routes.AudioSourceRoutes.GetAllByUserRoute}")]
	Task<IEnumerable<AudioSource>> GetAllByUserId(UserId userId, CancellationToken cancellationToken);
}

This works quiet fine as long as I define the "userId" as a Guid. Preferably when working with strongly typed IDs I want to use the UserId here, but this results in Exceptions which I think Refit is producing.

Refit.ApiException: Response status code does not indicate success: 400 (Bad Request). at Refit.RequestBuilderImplementation.<>c__DisplayClass14_02.<b__0>d.MoveNext() in /_/Refit/RequestBuilderImplementation.cs:line 288
--- End of stack trace from previous location ---
`

I guess Refit is not able to convert the UserId correctly to a Guid, even that I have included the Converters within my RefitSettings. Do I miss something here or is Refit not meant to be used with this feature?
