### Describe the feature request
Hello
It's been almost almost a year now that Lambda authorization for AWS AppSync has been released.
We have implemented Lambda auth for our web app but would like to be able to use Lambda authorization for our mobile apps as well.
Could you please provide an ETA of when AWS Lambda authorizer configuration will be added to amplify-android?

The issue provides no file, test, or entry point to start from, and asks for an ETA rather than defining implementation details. Clarify the supported AWS AppSync Lambda authorization configuration and acceptance criteria before locating the relevant Android GraphQL code and tests.
