Trigger event on the basis of fields

Hello Everybody

We are using and Event based architecture .

Where a Sales order is created it should Trigger an Event in Event Mesh .

But we want to trigger events when Sales Order are to be created by a certain User (CreatedBy field)

How can we achieve this .

Can we use change Pointer , Then we want to do only config , but not write any code (because that wont follow the Clean Core approach)

By any chance can we use the service descriptor given by Makoto Sugishita
