Get preview data with GraphQL

[Tobi-mmt]

Hey. I want to access my Sanity data via GraphQL. It works fine for the deployed content.
But if I want to access the preview data the documentation has no information about that. The only thing I found was examples with GROQ.

Thinks I tried:

• the definePreview or usePreview function of next-sanity/preview just works for GROQ
• I have not found a @preview directive for the GraphQL endpoint
• I can not see filters except the is_draft document filter, which is not right, because I don't want to see ONLY drafts, I want the most current data INCLUDING drafts

Is there a way to access preview data with the Graphql Endpoint of Sanity?
