How to pass some property on startup class and initialize it on controller

[KamranShahid]

I have a .net core 3.1 background application where i am spanning kestrel server as per implementation.
What i need is to initialize some property (let's say int channel id) when it is configured at startup

internal class Startup
{
    internal static IHostBuilder CreateHostBuilder(MyConfigurations _objSettings)
    {
	
   //_objSettings.channelId need to be assigned to CallBackController channelID
        return Host.CreateDefaultBuilder().ConfigureWebHostDefaults(webBuilder => webBuilder.UseUrls(_objSettings.CallbackLocalListener).
        UseStartup<Startup>());
    }

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllers(options => options.RespectBrowserAcceptHeader = true);
        services.Configure<ForwardedHeadersOptions>(options =>
        {
            options.ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto;
        });
    }

    public void Configure(IApplicationBuilder app)
    {
        app.UseHttpsRedirection();
        app.UseRouting();
        app.UseForwardedHeaders();
        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllerRoute("default", "{controller=Home}/{action=Index}/{id?}");
        });
    }
}


[Produces("application/json")]
public class CallBackController : ControllerBase
{          
int channelId = 0;//this need to be initializes 

    public IActionResult Receive()
    {
        IActionResult result = null;
       
        return result;
    }
}

I needed this as same class multiple instances will be starting kestrel instance on other ports listening different traffic. At the time of request receive i need that channel Id to initialize something
