SAP IDOC write how to set snap SAP IDOC to Asynchronous mode

Hi , Hi Team, I created one pipeline which writes an IDoc to SAP using SAP IDoc Write Snap.
I need to know how to set SAP IDOC to Asynchronous mode?

From the documentation:

This Snap writes an SAP IDoc to the configured SAP server. Because IDocs are processed asynchronously on the server, Polling interval and Polling timeout are additional configurations that define how to get the processing status.

Are you not seeing it behave that way?
