How to use the emojibase.fetchFromCDN function in emojibase

// We must use a variable here, otherwise webpack attempts to include it in the bundle.
      // If that happens and the module does not exist, it will throw a warning.
      // https://github.com/webpack/webpack/issues/8826

      const requireFunc =
        // eslint-disable-next-line @typescript-eslint/camelcase
        typeof __webpack_require__ === 'function' ? __non_webpack_require__ : require;

      testData = requireFunc('emojibase-test-utils/test-data.json');
    } catch {
      testData = [];
    }

    request = Promise.resolve(testData);
  } else {
    request = fetchFromCDN(`${locale}/${set}.json`, version);
  }

  promises.set(
    key,
    request.then(response => {
      const instance = EmojiDataManager.getInstance(locale);

      instance.parseEmojiData(response);

      return instance.getData();
    }),
  );

  return promises.get(key)!;
}

// Abort as we've already loaded data
        if (loaded.has(key) || emojis.length > 0) {
          this.setEmojis(emojis);

          return Promise.resolve();
        }

        // Or hook into the promise if we're loading
        if (promise.has(key)) {
          return promise.get(key)!.then(() => {
            this.setEmojis();
          });
        }

        // Otherwise, start loading emoji data from the CDN
        const request = fetchFromCDN(`${locale}/${set}.json`, version)
          .then(response => {
            loaded.add(key);

            this.getDataInstance().parseEmojiData(response);
            this.setEmojis();
          })
          .catch(error => {
            loaded.add(key);

            if (throwErrors) {
              throw error;
            }
          });

        promise.set(key, request);
