我有一个包含源代码的页面，如下面的代码。在执行操作后，在其中显示“撤消”和“关闭”按钮。我试图单击“关闭”按钮。我已经尝试了下面的所有三个代码块，但都无法正常工作。有人可以指出我做错了什么，还是建议其他尝试？

html来源：

<div><div><i></i><div>Your stuff is going to <span>place</span> is on its way.</div><div><button> Undo</button></div><div><button> Close</button></div></div></div>

代码尝试：

#driver.find_element_by_id("gh69ID1m3_xtdTUQuwadU").click()
driver.find_element_by_css_selector(''.c-button.c-button--blue'').click()
#driver.find_element_by_link_text(''Close'').click()

错误：
