How to immediately send a message to the user when unsubscribing from the channel from the Telegram Bot?

Question

Python

Can the bot immediately send a message to the user if he unsubscribes from the channel?
I've seen this somewhere and I think it's possible.
If so, can you advise how to implement it?

PS I wanted to do it through a loop, but in my opinion this is a bad idea, since there are more than 1000 people in the bot.

Haven't seen this feature.
But in theory, you can organize either a button or the "/unsubscribe" command, then you can write something to the user before the kick from the bot.
