How to make "endless" online in Telegram?

Question

Python

I need to make it permanently online in Telegram, so that when I close the application, it remains online. I know for sure that this can be done with vk, even in the telegram itself there are bots for this. Maybe someone has a bot that works on the same principle for a cart? Or maybe do something differently .. Maybe someone can write a bot? If there are people who can help, unsubscribe, please.
