title: Doesn't appear on your model definition nor it's relations (Strapi)
body: <p>Please help me with this. In my strapi graphql. How can I filter data based in nested data. I want to filter data base in relationship under tours -> tour_itineraries -> itineraries -> country -> Name.
  I want to filter it by country name. So I try this.</p>
  
  <p><strong>tours( where: { tour_itineraries: { itineraries: {  country: "Japan" } } } )</strong></p>
  
  <p>but it gives me error</p>
  
  <blockquote>
    <p>Your filters contain a field 'tour_itineraries.itineraries.country' that doesn't appear on your model definition nor it's relations</p>
