/**
 * @class FirebaseStorageStore
 * @param {Object} options - Options for the store
 * @param {FirebaseStorage} options.firebaseStorage - A Firebase Storage instance
 * @param {string} options.sessionPath - Path inside the storage bucket to store the session files
 * @returns {FirebaseStorageStore}
 * @example
 * import { Client, RemoteAuth } from 'whatsapp-web.js';
 * const client = new Client({
 *   authStrategy: new RemoteAuth({
 *     store: new FirebaseStorageStore({
 *       firebaseStorage: getStorage(app),
 *       sessionPath: 'sessions-whatsapp-web.js', // save in a sub-directory
 *     }),
 *     backupSyncIntervalMs: 600000, // 10 minutes
