Hello Hasura team!
First of all, many thanks and congrats on the wonderful work you did to deliver his engine (and of course your platform!)
I am running a cluster on v0.15.34 and try to connect to the data graphql endpoint (running on graphql-engine then).
I cannot run a query with '__typename' in it, for example:

query Profile {
  profile {
    id
    first_name
    __typename
  }
}

it sends me back that I have no permission to access '__typename' column:

{
  "errors": [
    {
      "path": "$[0].args.columns[2]",
      "error": "no such column exists : \"__typename\"",
      "code": "permission-denied"
    }
  ]
}

I assume the use of __typename is not implemented, but this is a big problem to me, as the entire apollo case system relies on the use of this property...
Have I missed something? If not, any plan to add this into your product?
Once again, many thanks for this project, I dreamt of it and you are making it real!
