In addition to captcha and ip on clients, how can you protect yourself from bots for a telegram bot?

Question

Information Security

People, I have a bot, but I found that even captcha does not help from bots and bots still connect.
There was an idea to make protection against bots by ip, but then I thought that ip could seem to be identical if people are sitting on the same network and it’s not a fact that you can get it in telegram. What are the possibilities besides the captcha, or maybe someone knows a difficult captcha for protection against bots, is there a package?

I myself use https://www.npmjs.com/package/nodejs-captcha
