The NWC goes in the app wallet in Settings. For the Nossie AI, when in the Settings page, click to settings widget in the upper right to find the Nossie setup. Once in there, the field entry works just like in Routstr, where an ecash token is accepted as the API. The base URL address in the Nossie setup doesn't auto-populate correctly. It looks like it's entered in, but is showing what has to be typed in exactly in that text box.
