How can I break out of question loop on ENTER using inquirer.js?

Question

I have the following task:

To terminate the procedure for adding users, it is enough to press ENTER instead of entering a name.

But when I use when in my code, the question is not displayed even the first time. Help me, please.

const questions = [
  {
    type: 'input',
    name: 'user',
    message: 'Pls, enter the user name or press ENTER to cancel:',
    default: 'nnnnn',

    validate: answer => {
      if (answer === '') {
        return 'Pls, enter a valid name';
      }
      return true;
    },
    // when(answers) {
    //   return answers.user === '';
    // },
    when(answers) {
      answers.user === '';
    },
  },
  {
    type: 'list',
    name: 'gender',
    message: 'Pls, choose the gender:',
    choices: ['male', 'female'],
    default: 'male',
  },
