title: editMessageText a simple example js
body: <p>I really need a complete simple example(code) for bot.editMessageText/ReplyMarkup usage.
  I use node.js, no framework, with standard telegram-bot-api module for Telegram
  Shortly, somthing like this:</p>
  
  <pre><code> let mes_id = 0;
   bot.onText(/\/start/, (msg)=&gt;{
       bot.sendMessage(msg.chat.id, 'Some text')
       mes_id = msg.message_id
   })
   bot.onText('edit',(msg)=&gt;{
       bot.editMessageText(msg.chat.id, mes_id, 'edited text'); //?!?! 
   })
  </code></pre>
  
  <p>I want previously sent message by bot to be edited, and could not find a full and understandable example on the internet.</p>
