Retrieve documents for a specified connection. Results are paginated (100 per page). Filter by date types: 'UPDATED_DATE', 'CREATED_DATE', 'BILL_DATE' (default), or 'USAGE_PERIOD'. Date filters return overlapping data; 'CREATED_DATE' and 'UPDATED_DATE' use UTC and are truncated to day start. Filter by 'isDeleted' to include/exclude soft-deleted documents. User must have connection access to view documents.
