Answer 1

During the initial authorization, write access_token, refresh_tokenand expires_inin SecureStore
Next, in the requests, check whether it has expired expires_in- if it has expired, make a request to refresh the token by updating the data in SecureStore, if it has not expired, make a request with the current token
Check for request errors if the request has not passed (for example, a token revoked) – also send a request to refresh the token
