Retrieves all playback IDs associated with a given media asset, including each playback ID’s access policy and detailed access restrictions such as allowed or denied domains and user agents.

How it works:

1. Send a GET request to this endpoint with the target mediaId.
2. The response includes an array of playback ID records with their respective access controls.

Use case: Useful for validating and managing playback permissions programmatically, reviewing restriction settings, or powering an access control dashboard.
