Get Graphql schema for the particular role from Hasura unauthenticated

[mjpolak]

Hi,

Is there a way to configure Hasura to allow export schema for the particular roles without authentication?
Ideally, it would be best to be able to set permission for an anonymous role with permission to access the schema.

Our use case is:
I'm configuring codegen tool to load schema and generate client code, it would be used on developer machines - I don't want them to authenticate each time they want to generate code.

Thank you in Advance!
