title: How can an app know it has the permission to enter autonomous single app mode(ASAM)?
body: <p>I know that an app can enter autonomous single app mode when MDM server grants it using "autonomousSingleAppModePermittedAppIDs". 
  I'm thinking that whether there is a way for an app to find it's whitelisted. Consider that my app is already running for a long time, then MDM server whitelist it, how can my app know that? Is there any notification? Thanks a lot!</p>
