Currently to trigger a new/empty search/lookup/response with FastGPT you need to click on the Kagi Labs icon which is above (and to the side if on PC). Clicking on FastGPT does nothing. This is not intuitive as the 'product' being used is FastGPT, not Kagi Labs.
Clicking on the FastGPT logo should also clear the search prompt making itself ready for a new prompt.
