Open Chromium with selenium in read-mode

My goal is to be able to get the main text content of a webpage without anything else. Firefox do this using with the reader view feature. It seems that Chrome haves this as experimental feature. Despite activating the feature from code, the icon doesn't show up.

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service as ChromiumService
from webdriver_manager.chrome import ChromeDriverManager
from webdriver_manager.core.utils import ChromeType

chrome_options = Options()
chrome_options.add_argument("--reader-mode=true")
chrome_options.add_argument("--enable-reader-mode")

driver = webdriver.Chrome(service=ChromiumService(ChromeDriverManager(chrome_type=ChromeType.CHROMIUM).install()), options=chrome_options)
driver

url = "https://www.google.com"
driver.get(url)
print(driver.page_source)
driver.quit()

The command line information chrome://version/ in are showing the parameters :

Command Line    
/Applications/Google Chrome.app/Contents/MacOS/Google Chrome --allow-pre-commit-input --disable-background-networking --disable-client-side-phishing-detection --disable-default-apps --disable-hang-monitor --disable-popup-blocking --disable-prompt-on-repost --disable-sync --enable-automation --enable-blink-features=ShadowDOMV0 --enable-logging --enable-reader-mode --log-level=0 --no-first-run --no-service-autorun --password-store=basic --reader-mode=true --remote-debugging-port=0 --test-type=webdriver --use-mock-keychain --user-data-dir=/var/folders/qx/y0sp0wpn5g524st9yn6f3cdm0000gn/T/.com.google.Chrome.L3pFOZ --flag-switches-begin --flag-switches-end

chrome://flags/ doesn't show the reader mode activated. Even if I activate it manually and restart, the reader mode icon is not shown in the binaries as well as Chrome on mac.

Is this feature still exists? If yes, how do I use it from selenium?
