am using API which allows me to collect data about countries. If i want get data about languages and currencies from different countries there is a problem because for example currencies in Poland has

currencies: PLN: {name: 'Polish złoty', symbol: 'zł'}

and for Portuguesa has

EUR: {name: 'Euro', symbol: '€'}.

How can i get data about currencies by code below no matter to countries? (In code i have written 'THERE IS A PROBLEM WITH CURRENCIES' this are places which i have repair.)

const btn = document.querySelector('.btn-country');
const countriesContainer = document.querySelector('.countries');

///////////////////////////////////////
const getCountryData = function (country) {
  const request = new XMLHttpRequest();
  request.open(
    'GET',
    `https://restcountries.com/v3.1/name/${country}?fullText=true`
  );
  request.send();

  request.addEventListener('load', function () {
    console.log(this.responseText);

    const [data] = JSON.parse(this.responseText);
    console.log(data);

    const html = `
  <article class="country">
    <img class="country__img" src="${data.flags.svg}" />
      <div class="country__data">
        <h3 class="country__name">${data.name.common}</h3>
        <h4 class="country__region">${data.region}</h4>
        <p class="country__row"><span>👫</span>${(
          +data.population / 1000000
        ).toFixed(1)} people</p>
        <p class="country__row"><span>🗣️</span>${
          THERE IS A PROBLEM WITH LANGUAGE
        }</p>
        <p class="country__row"><span>💰</span>${THERE IS A PROBLEM WITH CURRENCIES}</p>
      </div>
    </article>
    `;

    countriesContainer.insertAdjacentHTML('beforeEnd', html);
    countriesContainer.style.opacity = 1;
  });
};
getCountryData('portugal');
getCountryData('poland');
