Before Creating the Enhancement Request

• I have confirmed that this should be classified as an enhancement rather than a bug/feature.

Summary

SendMessageContext supports both transactional messages and delayed message types.

Motivation

Currently, when setting msgType in SendMessageContext, only normal messages and ordered messages are distinguished. Transactional messages and delayed messages are not differentiated.
In subsequent implementations of the send message hook, it won't be possible to differentiate the actual message type.

Describe the Solution You'd Like

When setting the message type for SendMessageContext, differentiate between transactional and delayed messages.

Describe Alternatives You've Considered

No
