Refresh token is not returned when renewing the access and id tokens
A refresh token is used to get the new access and id tokens when a current access token is already expired. A refresh token is meant to be used once and then discarded, therefore a new refresh token is expected along with the access and id tokens. Refresh token is not returned when trying to renew the access token in AwS (see more details in the attached fileR1_issues_-_refresh_token.docx).
