Expand Tree REST Endpoints

System Services/Expand Tree
Hierarchical data relationships for a specific context can be displayed based on configurable tree definitions. An external user interface can retrieve content with minimal visualization recommendations, allowing the external application to render each tree node per its own configuration and rules. Since displays are application-specific, the information does not include action-related settings.
