How to use the lighthouse-logger.cross function in lighthouse-logger

let hasFailure = false;
  for (const results of groupedResults) {
    const url = results[0].url;
    const sortedResults = results.sort((a, b) => {

      const {level: levelB = 'error', auditId: auditIdB = 'unknown'} = b;
      return levelA.localeCompare(levelB) || auditIdA.localeCompare(auditIdB);
    });

    process.stderr.write(`${sortedResults.length} result(s) for ${log.bold}${url}${log.reset}\n`);

    for (const result of sortedResults) {
      hasFailure = hasFailure || result.level === 'error';

      const icon = result.level === 'warn' ? '⚠️ ' : `${log.redify(log.cross)} `;
      const idPart = `${log.bold}${result.auditId}${log.reset}`;
      const propertyPart = result.auditProperty ? `.${result.auditProperty}` : '';

        .filter(Boolean)
