I've recently built some project that also supports Nostr (https://getbirdfeeder.com, but more for the fun of playing with Nostr) but it feels very forced to use it for something like that. It feels like it's solving an issue that no team chat ever has.

> Buzz is built around a self-hostable Nostr relay. Every message, reaction, workflow step, code event and approval is stored as a cryptographically signed event. Human employees and agents receive the same basic identity structure, including their own key pairs, channel memberships and audit trails.
