Describe the bug

Similar to how amplify codegen creates the respective classes with query / mutation / subscriptions, can there be a documentation or sample inputs created with all the queries and minimal inputs i.e. only mandatory inputs so that the front-end dev or user would have a sample which they can check with? This helps in maintaining documentation / sample inputs for the AppSync APIs.
