Retool's HubSpot app currently only asks for a subset of available scopes when authorizing using oAuth. This creates a situation where the HubSpot resource UI offers API endpoints that are actually unavailable due to the missing scopes., such as the Subscriptions API which requires communication_preferences.read
scope that is not requested by Retool's own HubSpot app and is therefore unavailable.
