It's a bit difficult, I think each client uses a different NIP/kind events... 😕
i.e satellite.earth and Amethyst uses the same, but habla.news and Coracle uses another different for communities... 🤷

For the moment, try searching MiniBolt on "Groups" section using coracle.social

On satellite.earth and Amethyst (communities) it appears don't detect the posts, very confused.. The newly Nostr protocol 😅
