Order viewer's pull requests by when they were created

Hello,

I’d like the ability to order the viewer’s pull requests by the datetime in which they were created. For example:

query {
  viewer {
    pullRequests(last:30, orderBy:{field:CREATED_AT,direction:DESC}) {
      edges {
        node {
          title
        }
      }
    }
  }
}
