User login and verification. React native & Node.js(Express)



I am using Auth 0 for user authentication with React native.
In addition, Node.js (Express) is used for API on the server side.

We created and authenticated users from mobile applications and succeeded in verifying JWT on the server side.

However, it is not supported when you invalidate the user from the console screen of Auth 0 or when it is unconfirmed by mail address authentication.
Even in this case, JWT verification is possible on the server side, so it passes authentication.

In order to deal with this case, I think that it is necessary to make a request to the API of Auth 0 and check it.
For example, /userinfo endpoint.

Is my implementation considered generic?
Are there any reference page?
