使用Python+Selenium/SeleniumBase关闭UPS网站Cookies弹窗失败求助

我使用以下代码操作UPS追踪页面，传入虚假追踪单号后，已成功关闭聊天窗口，但始终无法点击Cookies弹窗的关闭（X）按钮，除最后一行代码外其余功能均正常。若已安装对应依赖包，可直接复制代码到.py文件中进行测试。

driver.get("https://www.ups.com/track?track=yes&trackNums=1Z12345E1512345676&loc=en_US&requester=ST/")
time.sleep(3)
# Create another loop to run based on which element is found.

print(f"UPS Element found")
