inquirer package, present questions based on previous answers

I'm using NPM 'inquirer' package in order to present the user various questions. One of them is a 'choices' selection. Is there a way to present follow up questions based on the 'choices' selection?

Here's my code:

    const { prompt } = require('inquirer');
require('colors');

const questions = [
    {
        type: 'input',
        name: 'appName',
        message: 'Enter application name:'
    },
    {
        type: 'input',
        name: 'appDescription',
        message: 'Enter app description:'
    },
    {
        type: 'input',
        name: 'appAuthor',
        message: 'Enter app author:'
    },
    {
        type: 'checkbox',
        name: 'plugins',
        message: 'Select plugins to install:',
        choices: [
            {
                name: 'Cassandra'
            }
        ]
    }
];

module.exports.performQuestions = async () => {
    console.log('\nWelcome to Chef!\n'.underline.italic.cyan);

const answers = await prompt(questions);
if (!answers.appName) {
    console.error('\nPlease provide app name!\n'.red);
    process.exit(1);
}

    answers.appType = 'service';

    return answers;
};

Here I want to present a few more questions if the user selects 'Cassandra' is that possible?

Thanks.

You can use "when" and like in the example bellow, the second question will popup only if "Cassandra" is selected:

const QUESTIONS = [
  {
    name: 'your-name',
    type: 'list',
    message: 'Your name:',
    choices: ['Batman', 'Superman', 'Ultron', 'Cassandra'],
  },
  {
    name: 'hello-cassandra',
    type: 'confirm',
    message: 'Oh, hello Cassandra!',
    when: (answers) => answers['your-name'] === 'Cassandra',
  },
]; 


inquirer.prompt(QUESTIONS)
  .then(answers =>
  {
    console.log(answers);
  });
