I have AWS Lambda function and I invoke it calling AWS API Gateway via REST API. For Lambda function I configured two aliases with versioning - QA and Prod.

API Gateway is configured with Lambda Proxy Integration Request. I know about AWS API Gateway stages feature and I create two stages (QA and Prod respectively), but I don't see any settings for Lambda aliases in stage configuration.

How can I specify QA Lambda alias for QA stage and Prod Lambda alias for Prod API stage?
