How should a refresh token work?

Question

JSON Web Token

Hello, I have a question about JWT technology.
The documentation says that tokens need two access and refresh. But when implementing it, I understand that this thing works differently.
Actually questions:
1) access token - is issued for a given period and is never renewed again? It just rots in an hour, for example, and that's it?
2) after it is rotten, can you update it (make a refresh)?
So this should work? Or somehow differently? I don’t see implementations from anyone where two tokens would be generated at once. Project on Laravel and React Native.

Answer 1

1) Yes
2) If it is rotten, then refreshToken is called and a new one is issued.

Answer 2

This does not apply to JWTs. JWT is a token format. Your question is related to the protocol it is used with - oauth2 or oidc
