This is a super simple extension that I cooked up to help myself find a Pfizer booking with the HotDoc website. It just refreshes the page once activated until a search result is returned, in which case it stops and notifies the user.
To use, install the extension in developer mode and open up a hotdoc search that won't return any results you don't want, it'll keep refreshing once you click on it in the extensions button (in the toolbar) until there's a search result.
Also note that sometimes the chrome may time the extension out and it'll stop refreshing. I have no idea why this happens, but clicking on "service worker" in the extensions settings panel and leaving the extension's console open seems to fix this and let it run for hours at a time.
