 This endpoint defaults to use offset-based pagination, yet also supports
 marker-based pagination using the `marker` parameter.
 
+The number of entries returned may be less than `total_count`. For example, if a user deletes items from a shared folder and is later removed as a collaborator, those deleted items will no longer appear in this endpoint’s results, even though they are still included in `total_count`.

 This operation is performed by calling function `get_trashed_items`.
