Delete persistence Journal events once life cycle of behavior

I have setup a Persistence behavior using Akka Persistence Typed. Persistence Id will be created dynamically and internally a Supervisor/Router manages the short lived child actors. Also I am applying the snapshot mechanism using snapshotWhen. The expectation is, once the lifecycle of the child actor is over, all the journal and snapshots events needs to be auto deleted ( related to child actor behavior). How to achieve this?
