I am building this Q&A app that I found on this Link for my dissertation: https://auth0.com/blog/react-tutorial-building-and-securing-your-first-app/#React-Introduction. And I cannot figure out WHY am I getting this error?

"TypeError: _Auth__WEBPACK_IMPORTED_MODULE_2___default.a.isAuthenticated is not a function"

Can anyone help me please?

I beg of you to help me PLEASE!!! I need it ASAP for my dissertation and I can't get by it or find anything online for it. Thank you!
