+   * Equivalent to `listFirebaseLinks`, but returns an iterable object.
+   *
+   * `for`-`await`-`of` syntax is used with the iterable to get response elements on-demand.
+   * @param {Object} request
+   *   The request object that will be sent.
+   * @param {string} request.parent
+   *   Required. Format: properties/{property_id}
+   *   Example: properties/1234
+   * @param {number} request.pageSize
+   *   The maximum number of resources to return. The service may return
+   *   fewer than this value, even if there are additional pages.
+   *   If unspecified, at most 50 resources will be returned.
+   *   The maximum value is 200; (higher values will be coerced to the maximum)
+   * @param {string} request.pageToken
+   *   A page token, received from a previous `ListFirebaseLinks` call.
+   *   Provide this to retrieve the subsequent page.
+   *   When paginating, all other parameters provided to `ListProperties` must
+   *   match the call that provided the page token.
+   * @param {object} [options]
+   *   Call options. See {@link https://googleapis.dev/nodejs/google-gax/latest/interfaces/CallOptions.html|CallOptions} for more details.
+   * @returns {Object}
+   *   An iterable Object that allows [async iteration](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols).
+   *   When you iterate the returned iterable, each element will be an object representing
+   *   [FirebaseLink]{@link google.analytics.admin.v1alpha.FirebaseLink}. The API will be called under the hood as needed, once per the page,
+   *   so you can stop the iteration when you don't need more results.
+   *   Please see the
+   *   [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination)
+   *   for more details and examples.
+   * @example
+   * const iterable = client.listFirebaseLinksAsync(request);
+   * for await (const response of iterable) {
+   *   // process response
+   * }
