Hello. We do not officially support taking Content objects in ChatSession.send_message, so the type hint is correct and intentional.

The rationale is: Content = parts+role. role is managed by ChatSession. This leaves parts. So send_message essentially takes a list of parts. A PartsType.

If you want to send manually-crafted Content objects to the model, consider using GenerativeModel.generate_content.

Does this make sense?

@Ark-kun Yes, thanks for the feedback. A clear and easy way could then be to use the parts attribute of the manually crafted Content object, which is a list of parts. By the way, the code to be adjusted is here in Microsoft Autogen
