Chat Transcripts in Salesforce

We have setup a complete integration of Amazon connect and salesforce using AC CTI adaptor in Salesforce. We have enabled chat contacts, and the chats are coming through. Upon accepting the chat, we have created CTI flows to created LiveChatTranscript in Salesforce. How do we get the entire chat transcript to be populated into the body field of liveChatTranscript object.

We could not find any details in the documentation anywhere.
