How to use distinct in GraphQL query?

Question

Here is query where I try to use distinct in graphQl query:

query{
    contacts(take: 10, distinct: true) {
        firstName
        lastName
        title
    }
}

But I am getting error:

{
    "errors": [
        {
            "message": "Unknown argument \"distinct\" on field \"contacts\" of type \"QuerySchema\".",
            "locations": [
                {
                    "line": 2,
                    "column": 21
                }
            ]
        }
    ]
}

GraphQL has no built-in sorting/filtering. It is up to the server to implement features like that, so if you're relying on a third party API and it doesn't support it then you will have to filter the response yourself.
