Send parameters and file for graphql

In the project https://lighthouse-php.com they have an example of sending files with Curl. How can I represent the same in Postman?

```
curl localhost/graphql \
  -F operations='{ "query": "mutation ($file: Upload!) { upload(file: $file) }", "variables": { "file": null } }' \
  -F map='{ "0": ["variables.file"] }' \
  -F 0=@my_file.txt
```

I don’t think Postman currently supports file uploads with GraphQL.
