How to use the fs-temp.template function in fs-temp

return new Promise((resolve) => {
    var dir = fsTemp.template('t2-sdk-%s').mkdirSync();
    resolve({
      path: dir,
      cleanup: () => {
        try {
          fs.removeSync(dir);
        } catch (e) {
          // If the folder no longer exists, or if the remove operation throws
          // some error, this is non-fatal to the user (the data will just
          // exist until the temp folder is cleaned) and so we swallow any
          // errors.
        }
      }
    });
  });
}
