Realm Admin API - Retrieve App Service Log doesn't erturn user_id in payload

https://www.mongodb.com/docs/atlas/app-services/admin/api/v3/#operation/adminGetLogs

Seems like user_id is only available as the query parameter but not returned in the response.

How can I query all logs happening to my app and know which user does what from the log I retrieve from this API? Or are there any other methods that I can retrieve such info?
