How to use the react-styleguidist/lib/client/utils/filterSectionsByName function in react-styleguidist

renderSections() {
    const { searchTerm } = this.state;
    const { sections, useRouterLinks } = this.props;
    // If there is only one section, we treat it as a root section
    // In this case the name of the section won't be rendered and it won't get left padding
    const firstLevel = sections.length === 1 ? sections[0].components : sections;
    const filtered = filterSectionsByName(firstLevel, searchTerm);
    return this.renderLevel(filtered, useRouterLinks);
  }
