How to use the electron-log.daemon function in electron-log

switch (options.verbose) {
    case 1:
      log.transports.console.level = 'debug';
      break ;
    case 2:
      log.transports.console.level = 'debug';
      process.argv.push('-printtoconsole');
      break ;
    case 3:
      log.transports.console.level = 'silly';
      process.argv.push('-debug');
      process.argv.push('-printtoconsole');
      break ;
  }

  log.daemon = log.info;

  log.debug(`console log level: ${log.transports.console.level}`);
  log.debug(`file log level: ${log.transports.file.level}`);

  return log;
