Can I check the items in a specific data catalog?

Yes! Use the `get_catalog_items` tool with the Catalog ID. Your agent will fetch the items and their metadata directly from your Bloomreach instance.

How do I see all the customer segments I have created?

Simply ask the agent to `list_segments` or `list_segmentations`. It will retrieve the definitions and names of the customer groups you've configured in the Engagement platform.

Does the integration allow exporting customer properties?

Yes. Use the `get_customer_properties` tool with a registered Customer ID. The agent will retrieve core properties like name and email based on your project configuration.
