title: Field 'translatableResources' doesn't exist on type 'QueryRoot'
body: <p>I installed the <a href="https://help.shopify.com/en/api/graphql-admin-api/graphiql-app" rel="nofollow noreferrer">Shopify GraphiQL App</a> in my Shopify store to test some GraphQL queries.</p>
  
  <p>I want to translate content via their API.
  Here is the documentation for it: <a href="https://help.shopify.com/en/api/guides/multi-language/translating-content-api#retrieve-a-list-of-translatable-resource-types" rel="nofollow noreferrer">https://help.shopify.com/en/api/guides/multi-language/translating-content-api#retrieve-a-list-of-translatable-resource-types</a></p>
  
  <p>Now, I want to query their first example in the documentation: <code>Retrieve a list of translatable resource types</code></p>
  
  <pre><code>{
    __type(name: "TranslatableResourceType") {
      enumValues {
        name
      }
    }
  }
  </code></pre>
  
  <p>And received this response:</p>
  
  <pre><code>{
    "data": {
      "__type": null
    }
  }
  </code></pre>
  
  <p>Also the second query isn't working: <code>Retrieve a list of translatable resources by their type</code></p>
  
  <pre><code>{
    translatableResources(first: 1, resourceType: PRODUCT) {
      edges {
        node {
          resourceId
          translatableContent {
            key
            value
            digest
            locale
          }
        }
      }
    }
  }
  </code></pre>
  
  <p>The error of the second query:</p>
  
  <pre><code>{
    "errors": [
      {
        "message": "Field 'translatableResources' doesn't exist on type 'QueryRoot'",
        "locations": [
          {
            "line": 2,
            "column": 3
          }
        ],
        "path": [
          "query",
          "translatableResources"
        ],
        "extensions": {
          "code": "undefinedField",
          "typeName": "QueryRoot",
          "fieldName": "translatableResources"
        }
      }
    ]
  }
  </code></pre>
  
  <p>When I installed the Shopify GraphiQL App, I picked all permissions (incl. <code>read_translations</code> and <code>write_translations</code> permissions).
  And I do have products in my store.</p>
  
  <p>Which setting is missing or what am I doing wrong?</p>
