How can I make the bot send me a message that I sent to him?

Question

Node.js

bot.on('message', async msg => {
    let prefix = '*'
    if (msg.content.toLowerCase().startsWith(prefix)) {
      let m = msg.content.slice(prefix.length);
      for (let cname in commands) {
        if (m.startsWith(cname)) {
          let args = m.slice(cname.length).split(' ').filter(Boolean);
          commands[cname].run(bot, msg, args);
        }
      }
    }
  })

this function needs to be redone for telegram (telegraf)
thanks in advance to everyone for the help
