Customizable AI Search Answer Footer / Contact Link

I want to be able to add a custom message or link (e.g., 'if you are unhappy with the answer and cannot find it in the article, click here to send your question to one of the team') to the end of the AI's response in the 'Ask me anything' bar on the help center. This would help users who don't find the AI's answer helpful to easily reach out to the team.
