Pretty sure I've come across this in a video in the last few weeks but I can't seem to find the video, nor the option in the GUI to do it. as in you can type what you want to "say" to the assist and you get an output of the results (ie if it uses a LLM for the conversation agent it tells you what it comes back width.
I see there is an Assist option in the developer tools, but it seems to be specifically showing what happens internally rather than sending to the conversation agent and getting results from a LLM etc.
Cheers
