Is there a guide I could reference showing secure integration between graphcool and aws lambda? i.e. creating specific access rights for graphcool (read/write) and seting it up as only user who can execute these lambda functions. As an example, something like this guide from MongoDB (https://www.mongodb.com/blog/post/serverless-development-with-nodejs-aws-lambda-mongodb-atlas) seems extremely useful.

@ilja thanks for the feedback! we'll release more material on this soon, as we start adding more features to mutation callbacks to handle this in an easier way
