DrKLO/Telegram ? reverse-engineered prompt

I want to build my own messaging app for Android using the official Telegram source code as a base. The goal is to create my own version, so please don't use the official "Telegram" name or their paper plane logo. The app should feel just as fast, simple, and secure as the original.

The README mentions a whole compilation process with a lot of steps, like getting an api_id, setting up Firebase, and dealing with keys and build variables. Can you just handle all of that technical setup for me? You'll need to generate any new credentials required and plug them into the code. Basically, just take this source repository and turn it into a fully functional, rebranded messaging app that I can compile and run.
