* The options accepted by the constructor are described in detail
* in [this document](https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#creating-the-client-instance).
* The common options are:
* @param {object} [options.credentials] - Credentials object.
* @param {string} [options.credentials.client_email]
* @param {string} [options.credentials.private_key]
* @param {string} [options.email] - Account email address. Required when
* using a .pem or .p12 keyFilename.
* @param {string} [options.keyFilename] - Full path to the a .json, .pem, or
* .p12 key downloaded from the Google Developers Console. If you provide
* a path to a JSON file, the projectId option below is not necessary.
* NOTE: .pem and .p12 require you to specify options.email as well.
* @param {number} [options.port] - The port on which to connect to
* the remote host.
* @param {string} [options.projectId] - The project ID from the Google
* Developer's Console, e.g. 'grape-spaceship-123'. We will also check
* the environment variable GCLOUD_PROJECT for your project ID. If your
* app is running in an environment which supports
* {@link https://cloud.google.com/docs/authentication/application-default-credentials Application Default Credentials},
* your project ID will be detected automatically.
* @param {string} [options.apiEndpoint] - The domain name of the
* API remote host.
* @param {gax.ClientConfig} [options.clientConfig] - Client configuration override.
* Follows the structure of {@link gapicConfig}.
* @param {boolean} [options.fallback] - Use HTTP/1.1 REST mode.
* For more information, please check the
* {@link https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#http11-rest-api-mode documentation}.
* @param {gax} [gaxInstance]: loaded instance of `google-gax`. Useful if you
* need to avoid loading the default gRPC version and want to use the fallback
* HTTP implementation. Load only fallback version and pass it to the constructor:
* ```
* const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC
* const client = new DiscussServiceClient({fallback: true}, gax);
* ```
