Why does this not work? According to the idea, it should output an embed with a greeting and give the role of "traveler" when a new user on server, but something goes wrong, either an error in the embed or in my bad code.

robot.on('guildMemberAdd', member => {
  const userId = member.id;
  const exampleeEmbedd = new MessageEmbed()
  .setColor('#53db56')
  .setTitle('  [👋] Приветствуем нового путника!')
  .setDescription(' Приветствуем вас <@!'+ userId +'>!\nДобро пожаловать на международный сервер режима Geopolitics. \nЗдесь вы можете присоеденится к существующему городу/государству, либо зарегистрировать свой город/государство.')
