      public void updateTokens(String accessToken, String refreshToken)
      This function must be called by the inheritor class after every operation to make sure that the tokens stay current. This method compares the access token with the one from the persistent store. If the incoming tokens are different, it will update the persistent store.
      Parameters:
      accessToken - The new access token
      refreshToken - The new refresh token
