Lookup-Based Printable Filtering in Freedom UI (Equivalent to Classic UI Behavior)

We have implemented a lookup-based filtering mechanism for Printables in Classic UI. The behavior is as follows:

• A lookup field (e.g., Stage) is used as a filter.
• Based on the selected lookup value, only the related Printables are shown.
• For example, if there are 15 Printables in total and the user selects the “To Be Signed” stage, the system dynamically filters and shows only the 2–4 Printables that are relevant to the “To Be Signed” attachments.

This works correctly in Classic UI.

Now our customer has migrated to Freedom UI, and we need to implement the same functionality there. We have searched both Academy and Community, but all available examples of Printable filtering appear to be limited to Classic UI. We could not find any reference or implementation guidance for achieving lookup-driven Printable filtering in Freedom UI.

Has anyone implemented a similar scenario in Freedom UI, where Printables are dynamically filtered based on a selected lookup value or stage?

Any guidance, architectural approach, or sample implementation (Client schema, DataSource filtering, or UI Handler logic) would be highly appreciated.
