How can I configure the swagger ui page for azure functions v3?

OpenAPI

I added OpenApi support to an Azure functions application (v3), using .ConfigureOpenApi() in Program.Main(). I use function decorations for the specific functions but how can I control the general API name, version etc, shown on ~/api/swagger/ui ?

Here is my Program.Main() code:

public static void Main()
       {

           var host = new HostBuilder()
               .ConfigureFunctionsWorkerDefaults(worker => worker.UseNewtonsoftJson())
               .ConfigureOpenApi()
               .ConfigureServices(services =>
                   {
                       services.AddLogging();
                   }
               )
               .Build();

           host.Run();
       }
   }

What I have tried:

I Can write it in YAML manually but I need is generating OpenAPI (includes metadata like API Name, Version etc) from the code
