How to prompt for user input at the bottom of the terminal screen while printing text from the top down?

I need to prompt for user input at the bottom of the terminal screen while still having any text being printed to be outputted at the top of the terminal screen to the bottom. This prompting needs to behave similarly to session.prompt_async and place nicely with an existing asyncio event loop handler while still supporting all the usual syntax highlighting and tab completion features. Is there some way I can do this or perhaps take in a prompt input within a bottom toolbar object?

Start by reviewing the session.prompt_async entry point and the bottom toolbar API, with attention to integration with an existing asyncio event loop. Determine whether a supported design can keep input at the terminal bottom while streamed output remains above it, preserving syntax highlighting and tab completion; done means the behavior is implemented or its API limitations are documented.
