title: Callback for user's responses in a telegram bot (Telegraf)
body: <p>I'm coding a telegram bot with Telegraf on node.js and I need to get some information about users. For example, the bot is asking them where they are from. Then, I want to wait for the user's response and store it in my db. However, I don't understand how to achieve that since I can't just use a <code>bot.on('text', ...)</code> because I'm asking multiple questions and need to differenciate responses afterwards. I found out that there are callbacks but all that I found is for buttons and keyboards. Thanks!</p>
