Data Designers accessible by API

Hello Community

Our standards and practices have gotten us an invite into the official data lake. However, I do not want that team to have access to all Gainsight data. My preference is to create a Data Designer that outputs to a custom object. These designs would give them the filtered data with specific columns and reduce confusion on what to query.

It does not look like the Data Designer objects are accessible by API. Can we please update these objects to be accessible?
