Best way to format GraphQL Payloads

I’m working with a few different GraphQL endpoints where are becoming much more common it seems in B2B applicaitons.

While GraphQL still uses just REST, formatting payloads in Arc is a bit difficult other than just using plain text and script port:

For example:
https://shopify.dev/docs/api/admin-graphql/unstable/queries/order?language=cURL
 

GraphQL looks like:
 

query {
  node(id: "gid://shopify/Order/148977776") {
    id
    ... on Order {
      name
    }
  }
}

but to support this in Arc, I need to use a script port with a string of:
 

{"query": "query { node(id: "gid://shopify/Order/148977776") { id ... on Order { name } } }

Which fair enough is simple for my example, but realistic GraphQL queries are much more complex. Any suggestions on how to potentially work with this format in Arc?
