For now, we will show apps with an active FGS or jobs that the user
should be aware of (ie. "user-visible jobs") in the exact same way.
Users will be able to stop the ongoing FGS and user-visible jobs
using the same button. This won't be used to show apps on TM, so
the JobScheduler implementation is empty.
We'll add the JobScheduler implementation in U.
