Registering Metafield via gql vs gadget db field?

  // Create metafield definition for product variants that are part of the bundle
  const componentReference = await shopify.graphql(
    `mutation ($definition: MetafieldDefinitionInput!) {
      metafieldDefinitionCreate(definition: $definition){
        createdDefinition {
          id
        }
        userErrors {
          message
        }
      }
    }`,
    {
      definition: {
        key: "componentReference",
        type: "list.variant_reference",
        namespace: "eliteBundle",
        name: "Bundle component reference",
        ownerType: "PRODUCTVARIANT",
      },
    }
  );
