how to parse the body on an email and click on a link inside the email with node.js imap

I am trying to fetch the body of the email and click on the link located inside the the email. I am using node.js Imap. I am able to get the Sender, To, Subject and Date fields but not the body of the email. Here is the code I'm working with:

const P = require("bluebird");

const Imap = require('imap');
const inspect = require('util').inspect
//const MailParser = require(mailparser).MailParser;


var config = {
    imap: {
        user: 'myGmail@gmail.com',
        password: 'mypassword',
        host: 'imap.gmail.com',
        port: '993',
        tls: true
    }
};

readInbox = (imap) => {
    console.log(`Reading from Inbox...`);

    P.promisify(imap.openBox, { context: imap })('INBOX', true)
        .then(box => {

            var fetch = imap.seq.fetch(box.messages.total + ':*',
                {
                    bodies: 'HEADER.FIELDS (FROM TO SUBJECT DATE BODY )',
                    body: true,
                    struct: false
                });

            fetch.on('message', function (msg, seqno) {
                console.log('Message #%d', seqno);
                var prefix = '(#' + seqno + ')';
                msg.on('body', function (stream, info) {
                    var buffer = ' ', count = 0;
                    stream.on('data', function (chunk) {
                        buffer += chunk.toString('utf8');

                        msg.once('end', function () {
                            console.log(buffer);

                        })


                    });

                    stream.once('end', function () {

                        console.log(prefix + 'Parse Header: %s', inspect(Imap.parseHeader(buffer)));

                    });
                });

                msg.once('attributes', function (attrs) {
                    console.log(prefix + 'Attributes %s', inspect(attrs, false, 8));

                msg.once('buffer message', function (buffer){
                    console.log(prefix + buffer, inspect(buffer) )
                })   

                });
                msg.once('end', function (attrs) {
                    console.log(prefix + 'finished');

                });
                fetch.once('error', function () {
                    console.log('Fetch error : ' + err);
                });
                fetch.once('end', function () {
                    console.log('done fetching the email!')
                    imap.end();

                })


            })

        }).catch(err => console.error("error", err));

};



const imap = new Imap(config.imap);

imap.once('ready', () => readInbox(imap));
imap.once('error', error => console.error(`Error in IMAP connection:`, error));
imap.once('done', () => console.log('Done.'));
imap.once('end', () => console.log('End.'));
imap.once('close', () => console.log('Close.'));

imap.connect();
