### Please describe your feature-request in detail.

I'm currently trying to integrate an Amazon Lex V2 with Amplify Chatbot component using the @aws-amplify/ui-components library in my Nuxt 2 project. However the chatbot does not render responses from the bot in the chat window. I have checked the network logs and i see responses coming through from the server. The component works with Lex V1 chatbots and displays all requests and reponses correctly. It would be great if we could get it to work in V2. Thanks!

### Please describe a solution you'd like.

_No response_

### We love contributors! Is this something you'd be interested in working on?

- [ ] 👋 I may be able to implement this feature request.
- [ ] ⚠️ This feature might incur a breaking change.

Start by reproducing the issue in the reported Nuxt 2 project using the @aws-amplify/ui-components chatbot and an Amazon Lex V2 bot. Compare the network responses with what the chat window renders; done means Lex V2 bot responses appear correctly while the existing Lex V1 behavior remains working.
