Lambda forAmazon Connect Chat Interactive Messaging [Lex V2]

An AWS Serverless Application Model (AWS SAM) template to deploy a boilerplate AWS Lambda and Amazon Lex V2 bot, enabling interactive message in Amazon Connect chat.

Interactive messages are pre-configured responses that your users can select from, making it easy for your customers to quickly resolve their issues through chat. Interactive messages can be designed using the new Amazon Connect Chat templates, which include several different customer display options (shared below), and are sent by Amazon Connect Chat using Amazon Lex chatbots.
