Is there a graphql file with all the built in types in Prisma? I'm using a graphql language server with Visual Studio Code. And it complains about the built in types, for example:

Unknown directive "unique". (KnownDirectives)

. Edit: Also posted it on the forum: https://www.graph.cool/forum/t/location-of-graphql-definitions-for-built-in-types-in-prisma/2808
