+### Permission check
+The `permissions check` command is used to identify resources that lack the appropriate permissions based on their type, name, or tags.
+
+This command is particularly useful for administrators when roles, actions, or permissions have been modified or newly configured. By running this command, administrators can easily verify which resources and actions are not protected by any permission configuration, ensuring that proper security measures are in place.

+driver_hourly_stats_fresh    FeatureView
