Display Query Variable on GraphQL Previewer

Proxyman version? (Ex. Proxyman 1.4.3)

Version 2.35.4 (23540)

macOS Version? (Ex. mac 10.14)

I hit mutation like below, but when I saw using the GraphQL previewer feature, the query variable was not displayed.
Is there any solution to help us see all the requests clearly?

Here the JSON body

{
  "operationName": null,
  "variables": {
    "input": {
      "title": "A Very Captivating Post Title",
      "body": "Some interesting content."
    }
  },
  "query": "mutation ($input: CreatePostInput!) {\n  createPost(input: $input) {\n    id\n    title\n    body\n  }\n}\n"
}
