Ask HN: Has Anyone Monetized a Microsoft Teams App

Looking to bring an app to the Teams App store directly(a feature/app) that is currently lacking and is being requested by several hundred screaming users on their community forums. The monetization opportunity is there, but I am unaware of any prior successful app monetization on the Microsoft Teams platform. On the contrary, there are a few bootstrapped startups that were founded on Slack Appstore(looking at you standuply!). And some that make decent money for the dev: (https://news.ycombinator.com/item?id=17346050) Looking for some precedence on Teams App Store here.
