Lex v2 only the content of the messages in the attribute of amazon connect

Question

I currently face an issue with my amazon connect and lex v2 stuff. The plan is to invoke the lambda the lambda gives me the message and I can refer back to it with the $.Attributes feature in my Get customer input block.

If I reference messages from my lambda of the lex v2 in amazon connect itself, it gives me the hole array like content, contenttype and so on. I only want and need the content itself because this is the json I need to display to the customer.

{ 'sessionId': 'string', 'messages': [ { 'content': 'string', 'contentType': 'CustomPayload'|'ImageResponseCard'|'PlainText'|'SSML', 'imageResponseCard': { 'title': 'string', 'subtitle': 'string', 'imageUrl': 'string', 'buttons': [ { 'text': 'string', 'value': 'string' }, ] } }, ] }

Here is the link to the docs: https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/lexv2-runtime.html

Is there anything from the amazon connect side which I can use to only display the content of the messages attribute?

Thanks :)
