FerminT/TelegramRAT — reverse-engineered prompt

Build me a Windows desktop app in C# that works like a consent based remote support tool for my own computers, using a Telegram bot as the control channel. I want to set my bot token and chat ID in a config file, have each device announce that it is online, and let me target one machine or all of them with a simple device ID.

Keep it focused on clearly legitimate admin tasks like showing a popup, getting basic system and IP info, taking a screenshot, listing drives, folders, files, downloading and uploading files in user approved locations, running a command or starting an app, reading clipboard text, and viewing startup items. Make the app obvious to the user, with a visible running state and a clear opt in flow.

Do not add stealth, persistence, self delete, anti analysis, keylogging, saved passwords, cookies, webcam, microphone, or WiFi password features. If you need details, look up current Telegram bot docs online and wire up a simple working version end to end.
