Set-PWDocumentState / Messaging services

Is there a way to enable the messaging services to work when changing the state of a document via a powershell script? Changing the state manually triggers the messaging services to function, but when the state is changed using Set-PWDocumentState it does not.

We were hoping this could work as part of some automation we are working on. The script works fine, it's a scheduled process but messaging is ignored. Looking for any ideas to enable some kind of notification to select staff.
