How to implement the interface of Oauth2.0 's refresh token?

problem description

In

Oauth2.0, when the access_token expires, you can use the previously obtained refresh_token to reapply for tokens. The problem now is that you don"t know how the authentication server reissues tokens to the client according to refresh_token.

the environmental background of the problems and what methods you have tried

after consulting some materials, I feel that the implementation is diversified. The refresh interface of the authentication server mainly returns the following kinds of data:
1, returns brand-new access_token and refresh_token.
2. Return the new access_token, but the refresh_token is old. (it is possible that the expiration time of the old refresh_token will be updated)
3, return the old access_token and the old refresh_token. (I feel that the previous access_token can still be used because the expiration time has been updated.)

what result do you expect? What is the error message actually seen?

I personally feel that the first two are similar in nature, and the third is the old one, but the update time is not very good.
which of the above ways is better to ask the god to advise me? Or is there a better way to achieve it?

remember that refresh_token has an expiration time, which is much longer than that of access_token.
first, there are APIs to get access_token and refresh_token, and then refresh access_token according to refresh_token
both xxxx_token have valid time

so the problem with LZ is: the interface of refresh_token returns
I personally think
the second way: return the new access_token, but the refresh_token is old. (it is possible that the expiration time of the old refresh_token will be updated)

would be better. Because now that the refresh API is called, I want to get a new access_token, but as to whether to return the old refresh_token, I think it depends on the number of times the refresh_token is used and the validity period.
means: the refresh_token uses n times to return new / remaining n seconds to return new
