Building an employee recognition program that actually lives in Teams?

HR asked me to set up some kind of peer recognition system where people can give kudos to each other. They want it inside Teams because thats where everyone already is. I spent a few hours looking at options, Power Automate flows with adaptive cards, custom bots, etc. but nothing feels clean or sustainable. Has anyone set up a recognition/kudos system thats actually integrated into Teams and not just a bot that posts to a channel?
