hello everyone! i'm using prisma with apollo-codegen and can't seem to generate typescript typings for custom scalars provided by prisma, such as DateTime. How do i manage this? The generated typescript looks like this:

export interface talksConnectionQuery_talks_edges_node {
  __typename: "Talk";
  id: string;
  youtubeId: string;
  title: string;
  createdAt: DateTime;
}

and

DateTime

is not defined anywhere.
