// Returns information about events across your organization in Organizations. You
// can use the filters parameter to specify the events that you want to return.
// Events are returned in a summary form and don't include the affected accounts,
// detailed description, any additional metadata that depends on the event type, or
// any affected resources. To retrieve that information, use the following
// operations:
//   - DescribeAffectedAccountsForOrganization (https://docs.aws.amazon.com/health/latest/APIReference/API_DescribeAffectedAccountsForOrganization.html)
//   - DescribeEventDetailsForOrganization (https://docs.aws.amazon.com/health/latest/APIReference/API_DescribeEventDetailsForOrganization.html)
//   - DescribeAffectedEntitiesForOrganization (https://docs.aws.amazon.com/health/latest/APIReference/API_DescribeAffectedEntitiesForOrganization.html)
//
// If you don't specify a filter , the DescribeEventsForOrganizations returns all
// events across your organization. Results are sorted by lastModifiedTime ,
// starting with the most recent event. For more information about the different
// types of Health events, see Event (https://docs.aws.amazon.com/health/latest/APIReference/API_Event.html)
// . Before you can call this operation, you must first enable Health to work with
// Organizations. To do this, call the EnableHealthServiceAccessForOrganization (https://docs.aws.amazon.com/health/latest/APIReference/API_EnableHealthServiceAccessForOrganization.html)
// operation from your organization's management account. This API operation uses
// pagination. Specify the nextToken parameter in the next request to return more
// results.
