Configuring HttpClient and IHttpClientFactory in Autofac using autofac.json

I’m working on an ASP.NET project using Autofac for dependency injection, and I have a service that relies on HttpClient. I’ve registered IHttpClientFactory in my Startup.cs and use it to create HttpClient instances for various purposes.
I want to move the configuration of HttpClient and IHttpClientFactory to autofac.json to centralize the registration and to keep my Autofac configuration organized. However, I’m unsure of how to correctly configure HttpClient in autofac.json to utilize IHttpClientFactory.

I’ve registered HttpClient in my Startup.cs:

builder.Register(ctx =>
            {
                var services = new ServiceCollection();
                services.AddHttpClient();
                var provider = services.BuildServiceProvider();
                return provider.GetRequiredService<IHttpClientFactory>()
                                .CreateClient("HomeSubscriberServiceHttpClient");
            }).As<HttpClient>();

I’m looking for guidance on how to correctly configure HttpClient and IHttpClientFactory in autofac.json to achieve the desired setup. Any insights, solutions, or suggestions would be greatly appreciated.
