   * @param {Object} request
   *   The request object that will be sent.
   * @param {string} request.parent
   *   Required. Resource name of the tenant under which the event is created.
   *
   *   The format is "projects/{project_id}/tenants/{tenant_id}", for example,
   *   "projects/foo/tenant/bar". If tenant id is unspecified, a default tenant
   *   is created, for example, "projects/foo".
   * @param {Object} request.clientEvent
   *   Required. Events issued when end user interacts with customer's application that

   *
   *   This object should have the same structure as [ClientEvent]{@link google.cloud.talent.v4beta1.ClientEvent}
   * @param {Object} [options]
   *   Optional parameters. You can override the default settings for this call, e.g, timeout,
   *   retries, paginations, etc. See [gax.CallOptions]{@link https://googleapis.github.io/gax-nodejs/interfaces/CallOptions.html} for the details.
   * @param {function(?Error, ?Object)} [callback]
   *   The function which will be called with the result of the API call.
   *
   *   The second parameter to the callback is an object representing [ClientEvent]{@link google.cloud.talent.v4beta1.ClientEvent}.
   * @returns {Promise} - The promise which resolves to an array.
   *   The first element of the array is an object representing [ClientEvent]{@link google.cloud.talent.v4beta1.ClientEvent}.
   *   The promise has a method named "cancel" which cancels the ongoing API call.

   *
