Usage QR CODE

Here is an example of how to use the BaileysClass:

import {BaileysClass} from '@bot-wa/bot-wa-baileys';

const botBaileys = new BaileysClass({});

botBaileys.on('auth_failure', async (error) => console.log("ERROR BOT: ", error));
botBaileys.on('qr', (qr) => console.log("NEW QR CODE: ", qr));
botBaileys.on('ready', async () => console.log('READY BOT'))

let awaitingResponse = false;

botBaileys.on('message', async (message) => {
    if (!awaitingResponse) {
        await botBaileys.sendPoll(message.from, 'Select an option', {
            options: ['text', 'media', 'file', 'sticker'],
            multiselect: false
        });
        awaitingResponse = true;
    } else {
        const command = message.body.toLowerCase().trim();
        switch (command) {
            case 'text':
                await botBaileys.sendText(message.from, 'Hello world');
                break;
            case 'media':
                await botBaileys.sendMedia(message.from, 'https://www.w3schools.com/w3css/img_lights.jpg', 'Hello world');
                break;
            case 'file':

                break;
            default:
                await botBaileys.sendText(message.from, 'Sorry, I did not understand that command. Please select an option from the poll.');

        await botBaileys.sendPoll(message.from, 'Select an option', {
            options: ['text', 'media', 'file', 'sticker'],
