Telegram bot to execute commands with "/cmd" and get the output

telegram-shell.py

# Installation: pip3 install python-telegram-bot
# Usage:        /cmd COMMAND
# Examples:     /cmd whoami, /cmd ls -la, /cmd echo "a" > a.txt 
from telegram.ext import Updater, CommandHandler
from telegram.ext.dispatcher import run_async
import subprocess

# Fill with your token after creating a bot using @BotFather
token = ""


def exec_cmd(command):
	try:
		sub_ = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE)
		subprocess_return = sub_.stdout.read()
		return subprocess_return.decode("utf-8") 
	except:
		return "There was an error executing the command"


#@run_async
def cmd(update, context):
	chat_id = update.message.chat_id
	command = " ".join(context.args)
	subprocess_return = exec_cmd(command)
	context.bot.sendMessage(chat_id, subprocess_return)


def main():
    updater = Updater(token, use_context=True)
    dp = updater.dispatcher
    dp.add_handler(CommandHandler('cmd',cmd))
    updater.start_polling()
    updater.idle()


if __name__ == '__main__':
    main()

I did pip3 install python-telegram-bot
but running on windows it writes:

ModuleNotFoundError: No module named 'telegram.ext.dispatcher'
