NOTES

It's questionable whether or not the messages are deleted permanently from TextNow's servers

---

Depending on your log in method you may have your full name and not username show up on your account page, you will need to hardcode the value on line 21 if that's the case

change: TEXTNOW_USERNAME: document.querySelector(USERNAME_QUERY_SELECTOR).innerText,
to: TEXTNOW_USERNAME: "MyUsername",

you can get your username from the any of the urls used in making api calls. see Network panel in your web browser's console or by going to Settings > Account from https://www.textnow.com/messaging
