If you want to add extra permission groups to your app you can use _AddPermissions in the main file of your app
An extreme example would be:
_AddPermissions("Share, USB, Network, Camera, Location, SMS, WakeLock, Shortcut, Vibrate, License, Bluetooth, Storage, Contacts, SmartWatch2, Sounds, Vending, Record, Phone, Accounts, Boot, Body")
This can be in a comment or in your OnStart function
To remove individual permissions you can use a build.json file
