private setActiveLang() {
    const cachedLang = this.storage.getItem(this.storageKey);
    const browserLang = getBrowserLang();
    const cultureLang = getBrowserCultureLang();
    const defaultLang = this.service.config.defaultLang;
    const activeLang = isFunction(this.config.getLangFn)
      ? this.config.getLangFn({
          browserLang,
          defaultLang,
          cultureLang,
          cachedLang
        })
      : cachedLang || defaultLang;

    activeLang && this.service.setActiveLang(activeLang);
  }
