To get a file from a Telegram server, you'll need to use the Telegram Bot API. First, you need to obtain the file_id of the file you want to download. You can get this from the message object when a user sends a file to your bot. Then, you can use the getFile method to get the file path and construct the download URL.

The easiest way to use a Telegram bot is to search for an existing one on the platform, and activate it. You'll find game bots that you can use to play games with friends on Telegram, translation tools, and many more. The best way to use a Telegram bot is to simply check out the ones you like, and try them out!
