'Process command on updated user input

I have a telegraph based bot that handles some commands just fine. I want the bot to be able to respond on edited message by user. How can I do it?

const { Telegraf } = require('telegraf');
const bot = new Telegraf(process.env.token);

...

bot.command('help', async (ctx) => {
    ctx.reply("use /help 1 or /help 2");
});
