Is it possible to query for draft posts using the graphql playground?

Just the question in the header, thank you!

To query draft posts in Prismic, you'll need to first add them to a release. You can learn more about releases in this guide.

Once you've added your drafts to a release, you can query them using the Prismic REST API endpoint to get the release ref.

To include the release reference ID in your queries using the ApolloClient, you'll need to add it to the headers of your request. This will allow you to retrieve your draft posts using GraphQL.
