[Feature Request] Thumbs Up/Down to like or dislike the AI completion

[amitjoy]

Reflex presents an innovative solution aimed at empowering Python developers to craft sophisticated user interfaces devoid of prior expertise in frontend development. However, I perceive an opportunity for enhancement within the chat application to facilitate seamless adaptation to diverse use cases. Therefore, I advocate for the integration of thumbs-up or thumbs-down icons to the LLM-generated messages, allowing users to express whether they liked or disliked the generated message. This addition would undoubtedly enrich the application's functionality, rendering it complete.
