If a user creates or update a product we trigger an event `_eventBroker.Subscribe<BaseProductUpdated>` but we need the user who did the change. What service or do we need to look in the History. And how do we get the last post from the base product on the history tab?

Litium version: 7.\*

You can use `Litium.Auditing.AuditService.GetSummary<BaseProduct>(systemId)`.
