I have a Python 3.11 script that:

• Launches a headless Chrome browser (via Selenium), with an authenticated residential proxy (using selenium-wire or a dynamic Chrome extension)

• Navigates to ai.invideo.io, clicks “Join with Google,” completes the OAuth login

• Extracts access/refresh tokens from localStorage and updates a MySQL database

• Loads all secrets (proxy credentials, Gmail password, DB password) from a .env file

I’ve already tested and confirmed the script works locally and via CLI on Railway.
What I need help with is deploying it properly as a Railway cron task that runs automatically every 6 hours and reliably executes the script each time, in a headless environment that supports Chrome, Selenium, proxy auth, and MySQL.
