Best way to isolate an android app - Island, Insular or Shelter

I installed Shelter to setup a work profile (literally for my work apps in my case).

But I would like to have additional profiles similar to the work one:

  • One for snoopy apps, like social media or streaming video subscription players.
  • One for map apps, so that they are the only thing that connects when I plug into Android Auto (which has been reported to suck in tons of data from your phone and report it back to Google and the automaker), so that it can see no other data.

The problem is that Shelter only allows ONE work profile. And the other option I know is to setup Multiple Users, but that literally shuts down the other users, so that any apps isolated that way would be shut down and of course I’d get no notifications if a work email or personal chat message arrived.

Are there any options for true “multiple” work accounts?
