Can be combined with classifier\_dimensions (must use the same classifier\_id) or used independently with standard dimensions. ## Fields | Field | Type | Required | Description | Example | | --------------- | -------------------------------------------------------------------------------------- | -------------------- | ------------------------------------------------------------------------------------------------------------------------- | ------------------------------------ | | `classifier_id` | *str* | :heavy\_check\_mark: | UUID of the classifier whose tags to filter by.
