can't get stream response since no examples.

Describe the feature or improvement you're requesting

I download the dev branch. and I built project from below example:
https://github.com/D7EAD/liboai/blob/main/documentation/chat/examples/create_chat_completion.cpp

one problem is I don't know how to call "AppendStreamData".
another problem is I don't know how to add "stream" parameter into request: oai.ChatCompletion->create

so, I can't get response as stream.

Waiting for update. thanks!

Additional context
