Juby210/SwiftBackupPrem ? reverse-engineered prompt

Build me an LSPosed module for Swift Backup that unlocks the premium features in the app. It should work with the newer app versions too, and if there’s more than one way to hook it, please make it reliable and easy to keep working.

I also want an option to use my own Firebase credentials instead of the app creator’s, so the module only talks to my own Firebase project. Make that setup smooth enough that I can follow it without needing to dig through a bunch of code, and include whatever basic instructions are needed for linking the credentials and enabling the custom URI scheme in Google OAuth.

If you need to check current docs or best practices while you build it, go ahead and look them up online. Keep the app focused on doing this one job well, and make sure the project is ready to compile and install cleanly.
