Invoice Act Bot is a private Telegram bot used by a small team to prepare invoices and acceptance acts and store the generated PDF documents in the owner's Google Drive.
The bot is not a public service: only Telegram users invited by the owner can use it.
The bot requests a single Google permission,
https://www.googleapis.com/auth/drive.file. With it the bot can see and manage only
the folder and files it created itself. It cannot read, list or change any other files in the
Google Drive.
