I am developing a chat bot with whatsapp-web.js, but I am having a problem. Node js

Question

I am developing a chat bot with whatsapp-web.js, but I am having a problem. I installed npm i whatsapp-web.js and npm i qrcode-terminal. The QR code is generated, I scan it with my phone, but after connecting, when I try to send a message, it does not send automatically.

Code:

const qrcode = require('qrcode-terminal');

const { Client } = require('whatsapp-web.js');
const client = new Client();

client.on('qr', qr => {
    qrcode.generate(qr, {small: true});
});

client.on('ready', () => {
    console.log('**Client is ready!**');
});

client.on('message', message => {
    if(message.body === 'Hello') {
        message.reply('Hello Guys!');
    }
});
 

client.initialize();

Normally, when the QR code connection is established, the message Client is ready! should be printed to the terminal. I am not seeing this message in the terminal and the bot is not responding automatically to the message "hello". If you could help me, I would be grateful.

After the QR code connection is established, the message Client is ready! should appear and it should automatically respond to the message hello.

WhatsApp Web was changed.

Modify selector in Client.js line 175 Now I used textbox as selector

const INTRO_IMG_SELECTOR = 'div[role=\'textbox\']'; //'[data-icon=\'chat\']';
