How to use the @lhci/utils/src/lighthouserc.js.loadAndParseRcFile function in @lhci/utils

function createYargsConfigArguments() {
  const simpleArgv = yargsParser(process.argv.slice(2), {envPrefix: 'LHCI'});
  /** @type {[string, (path: string) => LHCI.YargsOptions]} */
  const configOption = ['config', loadAndParseRcFile];
  // If they're using the config option or opting out of auto-detection, use the config option.
  if (simpleArgv.config || hasOptedOutOfRcDetection()) return configOption;
  const rcFile = findRcFile();
  // If they don't currently have an rc file, use the config option for awareness.
  if (!rcFile) return configOption;
  return [loadAndParseRcFile(rcFile)];
}

test: opts => {
      const rcFile = resolveRcFilePath(opts.config);
      if (!rcFile) return false;
      return Boolean(loadAndParseRcFile(rcFile));
    },
  },
