The Chat agent functionality is great and useful. with reference to UI I would expect this adapts to the site’s CSS like Font, color theme, chat bubbles etc. I was able to do some wrapper to look slightly modern, but would request more granular customization then simple limited color change.
Hi! Glad to hear you find the Chat agent functionality useful 
Regarding the UI, you can submit this as a feature request on our roadmap: https://agenticflow.featurebase.app/roadmap. We prioritize development based on user interest, so the more people vote on it, the sooner it’ll get built.
