tap() does not work here. only click() works. I guess this is why we cannot see the items are checked on the GUI. But after save the alarm, and then go to edit alarm, we can see the items are actually checked.
I already spent a while on investigating how to follow normal user's journey, but I stopped at this point since:
1. I'm not sure why tap() does not work here.
2. I cannot find the "OK" button.
More investigation are needed.
