The Application connector can execute a query for a given application. For instance, you could enter the application "IAM” which is the IAM application itself. In the query parameter, you can specify the Delete/Update query, or pretty much any query, which will then be run.
It does require Indicium so it cannot be using inside process flow started in the Windows GUI; only System flows in that case.
In Universal GUI, you can use the Application connector inside process flows as Indicium handles this process action.
