First, install the extension in your Chrome browser, and check if it works. Then chek the correct extension location. Then you can install it when launching the chromedriver like so:

chrome_options = Options()
[...]
chrome_options.add_argument('--load-extension=/home/user/.config/chromium/Default/Extensions/cjpalhdlnbpafiamejdnhcphjbkeiagm/1.43.0_0')
