How to implement the expectation from the user of photos

how do I implement the following: I am sending a message to the user, after which I need to wait for the photos to be sent (from 1 to 10)?

that is, I need to build a chain of actions and expectations of a response from the user

I tried to use next(), but it didn't help, because the ctx doesn't change

i wait photos only after user click the button (or other not important action)

example result:
bot: send me photo (or several):
user: photo or mediagroup
bot: thk u!

code example:

async (ctx, next) => {
  try {
    ctx.reply(' Приложите фотографии отправляемого заказа для передачи курьеру\n' +
      'ℹ Максимальное количество принимаемых фотографий = 10' +
      '\n❔ После отправки всех фотографий отправьте команду /finish');
                
      next();
  } catch {
    this.restartBot();
  }
}

After this block I must waiting photos from user
