How to fetch custom product attributes value using Graphql API?

[surajkreno8e26]

Hi,
I'm trying to add custom data for the products by using the concept of creating custom product attributes. I've created the custom product attribute with the code "product_title_hindi" and now I'm looking for the solution so that I can fetch the value of "product_title_hindi" in my products query.
Can anyone please let me know that how can I fetch the custom attributes data using Graphql?

P.S: I'm looking for the complete API based solution.

I'm trying the below query but that's not a correct way as it's throwing an error "message": "Cannot query field \"product_title_hindi\" on type \"ProductInterface\".",

{
  products(search: "", pageSize: 10) {
    total_count
    items {
      name
      product_title_hindi
      uid
      sku
      url_key
    }
    page_info {
      page_size
      current_page
    }
  }
}

Any help is much appreciated!
Thanks
