title: Read the messages of the public channels from Telegram
body: <p>I need to read the messages of some public channels in the application, as for example it happens <a href="https://tlgrm.ru/channels/tech" rel="noreferrer">https://tlgrm.ru/channels/tech</a> As I understood, the bot for this business will not work. You need to use client api, but everywhere that with the channel methods are connected everywhere you need channel_id but where do I get it I do not know, I only have channel names, and how do I get it from it id I did not find such a method.</p>
  
  <p>How can I get the channel's id by its name?</p>
