Databricks Lake House Data Clean Room Utilization

Hello.

Is it possible to do masking on column data, etc. for the data provided by the cleanroom creator
I am wondering because I don't think Delta shaling allows masking of column data.

Currently, Delta Sharing does not natively support column-level masking or row-level security directly within its sharing framework. This means you cannot apply masking dynamically to data shared through Delta Sharing at the protocol level.

You can refer below documentation for more details:

@ozaaditya 
Thank you for your response
Am I correct in understanding that the Databricks cleanroom uses Delta Sharing as its foundation, so it does not natively support column-level masking and row-level security directly within the shared framework, as Delta Sharing does? I guess.

Here is the document I was looking at to ask my first question.
