How to use the cldr.extractCurrencyInfoById function in cldr

const extractCurrencyDataForLocale = async locale => {
  // Get the list of all currencies.
  // NOTE: this list contains "old" currencies that are not in used anymore.
  const currencyInfo = cldr.extractCurrencyInfoById(locale);
  // Fetch list of currencies that are still in use, then use this list
  // to "remove" the outdated currencies from the previous list.
  const activeCurrencies = await fetch(
    'http://www.localeplanet.com/api/auto/currencymap.json'
  ).then(response => response.json());

  return Promise.resolve(
    Object.keys(activeCurrencies).reduce(
      (acc, key) =>
        // `currencyInfo` given by `cldr` may not contain any information based on the
        // currencyCode that we fetched from `currencymap.json`, so we have this definition
        // check in place.
        currencyInfo[key]
          ? Object.assign({}, acc, {
              [key]: {
                label: currencyInfo[key].displayName,
