request.txt

{
  repositoryOwner(login: "enzoftware") {
    ... on User {
      pinnedRepositories(first: 6) {
        edges {
          node {
            name
            description
            primaryLanguage {
              name
            }
            stargazers {
              totalCount
            }
          }
        }
      }
    }
  }
}

Doesn't work.
