I'm not sure how a user should use this feature? The ux feels a bit weird to me. Clicking on it just pastes the link (urlencoded - this should probably be fixed so it pastes the link normally) into the assitant and that's it.
Coming from a search result I don't know what the user could ask about it as they presumably weren't on the site yet and there's nothing prefilled by quick answer. Or if they were, returning to the result pages feels like it'd be the same amount of work as just going to the assistant normally. One could just run the prompt immediately with just the url but that's most likely going to summarize and there's already a better tool for that
