Genesys Audio Hook introduced Update Transaction Message recently and this change is breaking our existing system. We are trying to working around this situation but we are unable to see Update Transaction Message in the audio hook in our environment. We want to know how to enable Update Transaction Message for our audio hook or what are steps that needs to taken so that we start seeing Update Transaction Message.
