Combining godot game apk with another apk

Question

I am working on a subscription model for a game, wherein after a time period, the game locks-out unless renewed.

Now, I am not aware of any such capabilities in godot itself, so I have to write a helper app/service for subscription check. My problem is, how do I combine the game apk, and helper apk into one.

I am aware of combining two projects into one in AndroidStudio, but how to do this with Godot. Any pointers are highly welcome !!

How does your subscription server communicate? You may be able to just implement the lockout functionality in GDScript.
