accountSettings property
The QuickSight settings for this AWS account. This information includes the edition of Amazon QuickSight that you subscribed to (Standard or Enterprise) and the notification email for the QuickSight subscription. In the QuickSight console, the QuickSight subscription is sometimes referred to as a QuickSight "account" even though it's technically not an account by itself. Instead, it's a subscription to the QuickSight service for your AWS account. The edition that you subscribe to applies to QuickSight in every AWS Region where you use it.
