laravel broadcasting docs issue

https://laravel.com/docs/12.x/broadcasting#client-reverb

as u see inside this page it states the config for react

import { configureEcho } from "@laravel/echo-react";

configureEcho({
    broadcaster: "reverb",
    // key: import.meta.env.VITE_REVERB_APP_KEY,
    // wsHost: import.meta.env.VITE_REVERB_HOST,
    // wsPort: import.meta.env.VITE_REVERB_PORT,
    // wssPort: import.meta.env.VITE_REVERB_PORT,
    // forceTLS: (import.meta.env.VITE_REVERB_SCHEME ?? 'https') === 'https',
    // enabledTransports: ['ws', 'wss'],
});

but no such package exists? with the name of configureEcho

now should i use normal this config

import Echo from 'laravel-echo';

import Pusher from 'pusher-js';
window.Pusher = Pusher;

window.Echo = new Echo({
    broadcaster: 'reverb',
    key: import.meta.env.VITE_REVERB_APP_KEY,
    wsHost: import.meta.env.VITE_REVERB_HOST,
    wsPort: import.meta.env.VITE_REVERB_PORT ?? 80,
    wssPort: import.meta.env.VITE_REVERB_PORT ?? 443,
    forceTLS: (import.meta.env.VITE_REVERB_SCHEME ?? 'https') === 'https',
    enabledTransports: ['ws', 'wss'],
});

then for calling events like this?

const channel = window.Echo.channel(channelName)
            .listen('.ScriptOutputBroadcasted', (e) => {
                setOutput(prev => prev + (e.output || ''));
            });
