I made this example for the group from Brazil and maybe it can help someone here on the forum. The application makes queries of x in x times in the API and alerts if there are new deaths or new cases in a selected country. (Sound alert)
The application is in Portuguese, anyone who has time and can translate I appreciate it.

The API used in this example is NovelCOVID/API and the extracted data is from worldometers.
