Hey, VAPI team. I'm using your new workflow system and missing a crucial feature from the old assistant configuration, the ability to add filler words and backchanneling. These natural conversation features made our agents sound much more human. With the recent move away from linking assistance to workflows, there's currently no way to configure these features in the workflow nodes. Could you add settings for filler injection backchanneling directly in the conversation nodes? I'm specifically looking for the same functionality where the agent uses natural fillers like ah, let me see, and back channeling responses like, uh-huh. Got it. This would be super helpful for maintaining natural sounding conversations in the new workflow system.
