SnapPack for Read GraphQL API's

Did anybody already used SnapLogic Platform for Reading from GraphQL API’s. It seems there is no Snappack for GraphQL, I guess you can only manage by developing an custom/own GraphQL-Snap? Anybody have expierience with that?

Here is a sample SnapLogic pipeline that might give you an idea on how to query with GraphQL. I built the query dynamically in the mapper and called the GraphQL API through REST Post Snap.

Thank you very much. I will have a look on this!
