How could I implement a refresh token that works with the implementation of the access token shown in the FastAPI docs using `python-jose`?

Question

I am trying to implement a rotating refresh token with an access token (JWT) in FastAPI. However, for now I just want to get a standard refresh token implementation working with no rotation occurring.

The FastAPI docs have an example of the implementation for the access token. I have implemented this and it works fine.

But, how do I pass the refresh token in a similar fashion as a dependency to routes? Should the refresh token be placed in the same token payload when logging in as:

{
    "access_token": ...,
    "refresh_token": ...,
    "token_type": "bearer"
}

Or should they rather be separate routes with different payloads?

Any guidance, whether they are links or code snippets, would be greatly appreciated.

In summary, how could I implement a refresh token that works with the implementation shown in the FastAPI docs linked earlier?

I want to use the python-jose package and not fastapi-jwt-auth (which is frequently suggested online). This is because fastapi-jwt-auth is no longer receiving support and smaller supported forks of the package are not mature yet.
