If you really want back out what you put in, you can use a browser’s web developer tools → network, and monitor the requests and responses to the API URL that services the web page of “chat” when you switch between prompts (preset settings) and the values are pushed to the UI.
Another internal API gated to Oauth2->session token and browser signature - where API access could have made the system a bit more useful.
