@Artem Astapenko We need extend to the API and the FE a data model that can handle that data schemas can be nested. i.e. it's not always just table / columns, but can be nested. I have put up a draft PR to get your feedback on how you would prefer to work with this nested structure on the frontend. Can you take a look at it before our sync tomorrow so we can discuss it then and pick what we should do?
