Ability to filter articles returned from the Project Version Articles API endpoint based on reader group ID. This would ensure that only content permitted for a specific reader group is fetched and displayed in external applications such as chatbots. The current multi-step workaround using separate endpoints is complex and not optimal for their use case. Adding a reader group parameter directly to the endpoint would provide a cleaner and more efficient solution. This enhancement is especially important for scenarios involving multiple reader groups with dynamic content access control.
