How to trigger TransmissionReport in OTM/GTM?

Summary:

I am trying to generate the TransmissionReport back to the Integration system once the Transmissions are processed.

Content (please ensure you mask any confidential information):

I have set the following property: glog.integration.TransmissionReport="yes"

I have included the required XML tags into the Inbound data XML header as well, check below screenshot for reference. I've tried all possible combinations & values for the ComMethod & AckOption fields that I could find but none of them returned the TransmissionReport as a response while testing from postman.

The integration (Webmethods) team wants to receive the TransmissionReport at their end so that they can do the needful at their end.
