尝试修改登录按钮以获得标准的Google登录按钮时遇到很多问题。我查看了文档（https://developers.google.com/identity/toolkit/web/setup-frontend#customizing_the_ui），但仍然不太了解它。
下面的代码只显示了我的谷歌按钮（不起作用）和另一个登录按钮（工作）。如何正确修改脚本，以便google按钮是用于登录的按钮？

您正在执行的操作只会呈现登录按钮，单击此按钮将启动身份工具包以进行登录。
window.google.identitytoolkit.signInButton
signInOptions：[＆＃34;密码＆＃34;，＆＃34; google＆＃34;]仅用于登录小部件：
window.google.identitytoolkit.start
这将显示登录选项中配置的按钮。
如果您想修改原始登录按钮，可以使用css执行此操作，也可以设置自己的按钮并在点击时运行以下命令：
window.google.identitytoolkit.signIn()
