How to competently implement JWT Token Refresh?

Question

JSON Web Token

Good morning!
I'm working on implementing a small blog in React and Laravel. Now implemented a simple authorization and registration, everything works correctly.
For Laravel, I use the Tymon/JWT library , which provides the JWT capability. Upon authorization, I receive a token that has 1 hour left to live. In the settings, this time can be changed, you can even set it to infinite.
Questions from a teapot in JWT:
If the token lives only 1 hour, let's say that a certain user logged in, used it and put his laptop away for a couple of hours. When he turns on the laptop, he will have to log in again. It turns out that this is exactly the case.
To get a new token (Refresh Token) you need to have a valid one (not expired) when sending a request.
Can you please explain to me how Refresh Token works? How long should a token live? How to implement all this correctly? and... when should the token be refreshed?
Explain in simple language for you.
Thank you very much in advance!
