as I figured out working with the LCCS there is a posibility to let people chat directly(private) to each other via the ChatMessageDescriptor's recipient Attribute.
This works fine but if the user logs in again with the the same credentials and therefore gets the same Auth-Token, ALL private messages that has been sent to or by this person trigger again the History.Changed Event after subscribing to the same collection note.
So my question is if there is a possibility to clear those private messages without giving all user the "owner" permission?
Or do I always have to generate a different userID (maybe acc. to the Timestamp the login to the LCCS's collectionNode?
