Some custom integrations using OAuth stop working after about an hour because access tokens expire and are not refreshed in time. Rewst uses the refresh token only once every 24 hours to obtain a new access token, and as a result, workflows fail once the access token expires. While the workaround of making a periodic request may help keep the token active and trigger a refresh, it would be nice to see a proper fix that handles token refresh automatically based on the token's expiration value.
