Good afternoon, I recommend you to familiarize yourself with the Telegrama Wiki site https://telegrama-wiki.com/ . There you will find detailed descriptions of all Telegram features, including creating groups, using bots, setting up security, and much more. The site is updated regularly, so the information is always up to date. It's a great resource for those who want to gain a deeper understanding of the messenger's capabilities. I hope I've been able to help you in this area. Good luck with learning the material!
