Refresh token after expiration

[astrojuanlu]

Sometimes the backend produces errors like these:

oauthlib.oauth2.rfc6749.errors.TokenExpiredError: (token_expired)

Unsure how to address this, because according to the flask_dance docs:

The OAuth dance normally only needs to be performed once per user. Once the consumer has an access token, that access token can be used to make many API requests on behalf of the user. Some OAuth implementations put a lifespan on the access token, after which it must be refreshed, but refreshing an access token does not require any interaction from the user.

A bit lost here, any help is very appreciated.
