/// Asynchronously creates a <see cref="AdGroupBidModifierServiceClient"/>, applying defaults for all unspecified settings,
/// and creating a channel connecting to the given endpoint with application default credentials where
/// necessary. See the example for how to use custom credentials.
/// </summary>
/// <example>
/// This sample shows how to create a client using default credentials:
/// <code>
/// using Google.Ads.GoogleAds.V0.Services;
/// ...
/// // When running on Google Cloud Platform this will use the project Compute Credential.
/// // Or set the GOOGLE_APPLICATION_CREDENTIALS environment variable to the path of a JSON
/// // credential file to use that credential.
/// AdGroupBidModifierServiceClient client = await AdGroupBidModifierServiceClient.CreateAsync();
/// </code>
/// This sample shows how to create a client using credentials loaded from a JSON file:
/// <code>
/// using Google.Ads.GoogleAds.V0.Services;
/// using Google.Apis.Auth.OAuth2;
/// using Grpc.Auth;
/// using Grpc.Core;
/// ...
/// GoogleCredential cred = GoogleCredential.FromFile("/path/to/credentials.json");
/// Channel channel = new Channel(
/// AdGroupBidModifierServiceClient.DefaultEndpoint.Host, AdGroupBidModifierServiceClient.DefaultEndpoint.Port, cred.ToChannelCredentials());
/// AdGroupBidModifierServiceClient client = AdGroupBidModifierServiceClient.Create(channel);
/// ...
/// // Shutdown the channel when it is no longer required.
/// await channel.ShutdownAsync();
