    const translate = useTranslate();

    const points = 10000;
    const formattedPoints =
      i18n.formatNumber(points);
    // Translate the loyalty points message, using pluralization to differentiate messages
    const loyaltyPointsMsg = translate(
      'loyaltyPoints',
      {
        count: points,
        formattedPoints,
      },
    );
