如何仅用Selenium在无头模式下处理Chrome应用商店扩展添加弹窗

目前Stack Overflow上的相关方案，要么是用pyautogui这类工具点击添加扩展的弹窗，要么是通过ChromeOptions下载并加载扩展，但这些都满足不了我的需求。我需要在无头模式下完成扩展添加，而且因为某些原因没法下载扩展。试过相关帖子里的方法都没用，我的代码片段如下：

import time
import pyautogui
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.support.ui import WebDriverWait
from webdriver_manager.chrome import ChromeDriverManager
from undetected_chromedriver import Chrome, ChromeOptions
from selenium.webdriver.support import expected_conditions as EC

service = Service(ChromeDriverManager().install())

options = ChromeOptions()
options.add_argument("--disable-web-security")
options.add_argument("--disable-xss-auditor")
options.add_argument("--no-sandbox")

driver = Chrome(service=service, chrome_options=options)
driver.execute_script("Object.defineProperty(navigator, 'webdriver', {get: function() {return false}})")
wait = WebDriverWait(driver, 50)

driver.get("https://chrome.google.com/webstore/detail/chatgpt-chrome-extension/gabfffndnhbbjlgmbogpfaciajcbpkdn")
wait.until(EC.element_to_be_clickable((By.XPATH, '//div[contains(@class, "webstore-test-button-label") and contains(text(), "Add")]')))
driver.find_element(By.XPATH, '//div[contains(@class, "webstore-test-button-label") and contains(text(), "Add")]').click()

time.sleep(5)
pyautogui.hotkey('tab','enter', interval=0.1)
time.sleep(5)
driver.quit()
