LoginCustomerID issue

[Reports1]

Google Ads API team and all.
I have access to 3 Google Ads manager accounts. 
When getting Google Ads API data for each using C#/.Net client, it works only if for the specific manager customer in the App Config file:

  <GoogleAdsApi>
   <add key="LoginCustomerId" value="XXXXXXXXXX" />

I tried to populate it dynamically under "options". See info below,  but some how it gets ignored and Google API seems to only see/recognize the LoginCusomterID in the Apps.config.

I tried to add it in this section, but it is being ignored.

 codeExample.Run(new GoogleAdsClient(), options.CustomerId, options.LoginCustomerId,Start_date_new, End_date_new, DMS_STORE_ID);

when calling the API as is does not accept the LognincustomeriD under:

 googleAdsService.SearchStream(customerId.ToString(),query,
                    delegate (SearchGoogleAdsStreamResponse resp)

Appreciate any help, thanks

        public class Options : OptionsBase
        {
            [Option("customerId", Required = true, HelpText =
                "The Google Ads customer ID for which the call is made.")]
            public long CustomerId { get; set; }

            [Option("LoginCustomerId", Required = false, HelpText =
             "Optional Login customer ID if your access to the CIDs is via a manager account.")]
            public long LoginCustomerId { get; set; }

        }

     Options options = new Options();
                        CommandLine.Parser.Default.ParseArguments<Options>(args).MapResult(
                            delegate (Options o)
                            {
                                options = o;
                                return 0;
                            }, delegate (IEnumerable<Error> errors)
                            {

                                options.CustomerId = long.Parse("aaaaaaaa"); 
                                options.LoginCustomerId = long.Parse("XXXXXXXXXX);
                                return 0;
                            });
