How I can provide arguments towards the existing graphql request?

I made the followig schema.graphqls

type BlogPost {
    blog_post_id: ID
    title: String
    post: String
}

input BlogpostAttributeFilterInput {
    page: Int
    limit: Int
}

type Query {
    allBlogPosts(input: BlogpostAttributeFilterInput) :
    [BlogPost] @resolver(class: "\MageGuide\FirstModule\Model\Resolver\GetBlogPosts")
    @doc(description:"Retrieve All BlogPosts")
    @cache(cacheable: false)
}

And I want to provide some arguments towards the request allBlogPosts I tried in my tool:

{
    allBlogPosts(page:1,limit:10){
        blog_post_id
    title
        post
  }
}

But I got the following error:

{
    "errors": [
        {
            "message": "Unknown argument "page" on field "allBlogPosts" of type "Query".",
            "locations": [
                {
                    "line": 2,
                    "column": 15
                }
            ]
        },
        {
            "message": "Unknown argument "limit" on field "allBlogPosts" of type "Query".",
            "locations": [
                {
                    "line": 2,
                    "column": 22
                }
            ]
        }
    ]
}

How I can provide the arguments towards the request?
