I want to send system message after user response and before agent response to be able to control agent response on a per message basis

@jnetic_ Certainly! To enable backchanneling, which sends messages like 'mhmm', 'ahem', etc., while the user is speaking, you can set the

backchannelingEnabled

option to

true

. This will allow for a more natural and interactive conversation flow. Would you like me to enable this feature for you now?
