因此，在我的应用中成功Google Account linking之后，我使用Android设备对其进行了测试，没有任何问题。我使用了“ in conversation prompt”技术来请求用户进行身份验证以进一步进行操作。换句话说，我能够使用有效的accessToken（以及其他信息）成功地从Dialogflow接收响应的“用户”属性。
现在，我在Google Home设备上进行了尝试。该设备配置了与我在Android移动设备上使用的相同的电子邮件ID。当我调用G.Home时，它成功加载了该应用程序。但是这里缺少的部分是用户属性（下面的JSON）中的accessToken。在上述情况下，我假设以下情况：
由于我已经在Android移动设备上成功登录，因此下次我尝试在同一设备上调用该应用程序时，该应用程序不会提示您“登录”，因为它已经具有accessToken（直到过期）。并且由于我在G.Home设备上使用了相同的gmail地址，所以我也应该获得相同的accessToken。
只要使用相同的gmail地址，我自己使用哪种设备/界面进行Google身份验证都无所谓，如果访问令牌未过期，我将始终获得它。
我共享的上述链接中详细介绍了整个Google帐户链接的设置/配置。这是我分别在G.Home和Android设备上收到的JSON：

我的问题是，当我使用Google Home设备时，在哪里可以得到accessToken？
