Hi. New to prisma (2.15.0). Working through some things, having a hard time finding docs for env(…) in the prisma.schema. There’s reference to dotenv expansion - but can env support that? or do I need a .env file for that? Basically, what I’m hoping to avoid is having to define the DB_URL, since I’d rather build the dsn from the individual pieces in the code and not have to rely on .env file (for example)
