  userId: 'me',
  labelIds: ['UNREAD', 'CATEGORY_PERSONAL', 'INBOX'],
  maxResults: 10
});

if (res.data.messages) {
  const messages = res.data.messages;
  for (const message of messages) {
    const msg = await gmail.users.messages.get({
      userId: 'me',
      id: message.id
    });
    const mail = readGmailMail(msg.data);
