How to use the intl-messageformat.__addLocaleData function in intl-messageformat

locales.forEach(localeData => {
      if (localeData && localeData.locale) {
        IntlMessageFormat.__addLocaleData(localeData);
        // IntlRelativeFormat.__addLocaleData(localeData);
      }
    });
  }

locales.forEach((localeData: any) => {
      if (localeData && localeData.locale) {
        // @ts-ignore Inaccurate type information
        IntlMessageFormat.__addLocaleData(localeData)
      }
    })
  }

    for (var i = 0; i < arguments.length; i++) {

            throw new Error(
                'Locale data provided to IntlRelativeFormat is missing a ' +
                '`locale` property value'

        }
    
        RelativeFormat.__localeData__[datum.locale.toLowerCase()] = datum;

    }
