Is this the best place to ask questions regarding prisma? Or is there a help channel devoted to that?

Probably either this or #prisma-client

The best channels to ask questions about the Prisma ORM are indeed this Slack community (choose the channel according to your topic) or GitHub Discussions. If you're looking for answers to questions about the Prisma Data Platform, I recommend logging in and opening a chat in the UI. 🙂
