I need a small Telegram-based admin chat system whose sole focus is to manage user access. From a private admin chat (or inline commands) I want to be able to: • Grant or revoke membership for any user in my chosen groups or channels • See at a glance whether a user is currently allowed, banned, or muted • Receive immediate confirmation in the chat whenever access changes The workflow should feel effortless: I type a command, the bot carries it out, and the status update appears in the same thread. Whether you build it with Python (python-telegram-bot, Telethon, pyrogram) or another framework is up to you—as long as installation is straightforward and it runs reliably on a standard server (Linux, Docker, or another environment you recommend). Security matters, so hard-code admin IDs or provide a simple whitelist so only I can control the bot. Persistence of the access list between restarts is essential. Deliverable: source code, a brief setup guide, and a short demo showing the add/remove flow in action.
