I am converting my Product.all REST Admin API to a GraphQL API, and there are 5 fields that are not being fetched:

  1. grams
  2. inventory_management
  3. fulfillment_service
  4. requires_shipping
  5. weight_unit

These fields were available under the variants object in the product response in the REST API, but in the GraphQL API, these fields are not available under variants. How can I fetch these fields in GraphQL?
