[FIXED] aiogram - How to execute a function?

Issue

Update: After few uncessful attempts to explain the problem, completely rewrote the question:

How to execute a function on startup?

from aiogram import Bot, Dispatcher, executor, types

API_TOKEN = 'API'

bot = Bot(token=API_TOKEN)
dp = Dispatcher(bot)

@dp.message_handler()
async def echo(message: types.Message):
  await message.answer(message.text)

async def notify_message() # THIS FUNCTION
  # await bot.sendMessage(chat.id, 'Bot Started')
  await print('Hello World')

if __name__ == '__main__':
   notifty_message() # doesn't work
   executor.start_polling(dp, skip_updates=True)

Tried without success::

if __name__ == '__main__':
  dp.loop.create_task(notify_message()) # Function to execute
  executor.start_polling(dp, skip_updates=True)

AttributeError: 'NoneType' object has no attribute 'create_task'

if __name__ == '__main__':
  loop = asyncio.get_event_loop()
  loop.create_task(notify_message()) # Function to execute
  executor.start_polling(dp, skip_updates=True)

TypeError: object NoneType can't be used in 'await' expression

Solution

It was much simpler than expected. facepalm
Working Solution:

from aiogram import Bot, Dispatcher, executor, types

API_TOKEN = 'API'
bot = Bot(token=API_TOKEN)
dp = Dispatcher(bot)

@dp.message_handler()
async def echo(message: types.Message):
   await bot.send_message(message.chat.id, message.text)

def test_hi():
   print("Hello World")

if __name__ == '__main__':
   test_hi()
   executor.start_polling(dp, skip_updates=True)
