selenium定位这种标签该怎么写

我想定位这个上面的标签excel流式导出，这个标签缓冲好后才能点击，下面我写的代码但是定位不到
element = WebDriverWait(driver, 55, 4).until(ec.element_to_be_clickable((By.XPATH, '//*[@class="fr-btn-up fr-btn-text-icon fr-btn-over"]')))
print(element)
element.click()
真心不会啊，本人不太懂，能否全面解答下，谢谢

浏览器装个xpath插件，方便调试 https://blog.csdn.net/weixin_43847283/article/details/125571325

• 这个问题的回答你可以参考下: https://ask.csdn.net/questions/7683825
• 你也可以参考下这篇文章：python+selenium自动化测试，元素定位脚本都未写错但是报错。可能是页面元素未加载完成就去执行下一步。需要加等待
• 除此之外, 这篇博客: selenium处理网页下拉加载数据爬取并存入excel中的 完整代码 部分也许能够解决你的问题, 你可以仔细阅读以下内容或跳转源博客中阅读:
