The usage shown here no longer works due to changes in Roblox’s login system with ReCaptcha. noblox-js/roblox.js now use Roblox tokens for login, meaning you can’t both run this script and use your account at the same time. rbx.login(token) would need to be used instead.
This may seem like an annoying work-around but ReCaptcha has also resulted in a huge decrease in the volume of scams posted in general on group walls.
This post does a good job of explaining how to use tokens to login: https://devforum.roblox.com/t/guide-to-scripting-bots-javascript-tutorial-funcaptcha-and-new-host-info/58201
