Which statement about hidden columns in an Aggregate is correct?

Hiding columns in an Aggregate primarily impacts the visibility of those columns in the output preview within the development environment. When you hide a column, it does not affect the underlying data fetching or processing logic of the Aggregate; it simply makes the development view cleaner and more focused by displaying only relevant information.

The hidden columns still exist in the Aggregate but are not displayed in the output section, which allows developers to select what needs to be visible without altering the data retrieval functionality. This feature is useful for managing large datasets or when only specific pieces of data are necessary for a given context, maintaining clarity during development without disrupting the operational integrity of the Aggregate.
