Thanks Yannick // socIAty.io for the question! Currently, you can re-create a chat interface and plug it to your Dust agent through the API.
Unfortunately, there is no "easier" way to do it at this time. It's on the team's radar but isn't straightforward to crack given the potential pricing/cost impact. 😊
I will definitely share your feedback with them. Thanks for sharing your needs, it really helps the team prioritize!
