The change I am proposing is just a configuration change in settings.py. We
need to set JWT_ALLOW_REFRESH to True and determine what we want the
default value for JWT_REFRESH_EXPIRATION_DELTA to be. The first will enable
the feature, the second will determine the length of time that can pass
from the creation of the very first token (using name and password) until
the user has to use the username and password again. In the time in
between, the user can use the JWT to get a new JWT.

More docs on this are here[0].
