How to use the algoliasearch-helper.url function in algoliasearch-helper

createURL(state, {absolute}) {
    const currentQueryString = this.urlUtils.readUrl();
    const filteredState = state.filter(this.trackedParameters);
    const foreignConfig = algoliasearchHelper
      .url
      .getUnrecognizedParametersInQueryString(currentQueryString, {mapping: this.mapping});
    // Add instantsearch version to reconciliate old url with newer versions
    // eslint-disable-next-line camelcase
    foreignConfig.is_v = majorVersionNumber;
    const relative = this
      .urlUtils
      .createURL(algoliasearchHelper.url.getQueryStringFromState(filteredState, {mapping: this.mapping}));

    return absolute ? getFullURL(relative) : relative;
  }
