Give Default permissions to non-system Prebuilt Apks from frameworks

[Lavyansi]

I am building an aosp + vendor changes where I have many system and privileged Apps for Android -10 I have a few applications which are non-system and post loaded apps which I install later.

I want to give required permissions programmatically as I know the package names already. Any idea where exactly I need to make a change. I have access to the AOSP- source code.

Any ideas?

Check how this class already does this for some apps
