For the tutorial for creating the BigCommerce App, there is a function call verifyJWT. However, I cannot find that from the class here https://developer.bigcommerce.com/docs/ZG9jOjE4MjIyODMy-step-2-connect-your-app-to-big-commerce I tried to replace verify with verifyJWT on the tutorial that doesn't work. Is that such a function that we can use? A copy of the code from the tutorial: https://github.com/bigcommerce/sample-app-nodejs/blob/step-3-add-database/lib/auth.ts Screenshot <img width="1206" alt="main_full (8)" src="https://user-images.githubusercontent.com/28014862/169663515-b27ab001-1404-4965-8a67-a4aa220a28b3.png">
