            // the AI sometimes sends code blocks with newlines in them

Review comment (suggestion):
```suggestion
                concatenatedMessages += chatMessage.as<ChatMessage>()->MessageContent() + L"\n\n";
```

Do we want to add an extra newline to better separate each message? Personal preference of mine
