leonboe1/GoogleFindMyTools ? reverse-engineered prompt

Build me a Python tool that helps me work with Google Find My Device, now Find Hub, in a simple way.

I want to be able to log in with Google through Chrome, then see my trackers and Android devices, pull out their encrypted keys, and decrypt the location updates they send. It should also let me register my own custom trackers, especially ones made with ESP32 or Zephyr devices, and walk me through that from the app. Make it feel like a practical command line utility that I can run from main.py, with clear prompts and helpful messages when something is missing or not supported.

Please keep it experimental but usable, and make sure it saves the auth info so I can reuse it later on another machine if needed. If you need to check current docs or browser behavior, look them up online first.
