Give remote Chrome webdriver a capability to run with extension

I am trying to run a Chrome webdriver with extension and it is working on non remote setup, but as soon as I set up remote webdriver, it fails to start. Here is what system outputs:

selenium.common.exceptions.SessionNotCreatedException: Message: Could not start a new 
session. Error while creating session with the driver service. Stopping driver 
service: Could not start a new session. Response code 500. Message: unknown error: 
failed to wait for extension background page to load: chrome- 
extension://bfnaelmomeimhlpmgjnjophhpkkoljpa/_generated_background_page.html
from unknown error: page could not be found: chrome- 
extension://bfnaelmomeimhlpmgjnjophhpkkoljpa/_generated_background_page.html

Here is my driver.py file:

def initialize():
   global instance
   options = webdriver.ChromeOptions()
   prefs = {'download.default_directory': '/driver/extensions'}
   options.add_experimental_option('prefs', prefs)
   options.add_extention('path/to/extension')
   options.add_argument('--headless') 
   instance = 
   webdriver.Remote('http://localhost:4444/wd/hub', DesiredCapabilities.CHROME, 
   options=options) 
   # instance = webdriver.Chrome(options=options) # this is working 
   instance.implicitly_wait(2) 
   return instance

To make Chrome webdriver be able to run with an extension it should be non-headless.

This config should be removed:

options.add_argument('--headless')
