JSON-LD 中的事件描述似乎未在 Gmail 中进行解释

Event description in JSON-LD does not appear to be interpreted in Gmail

我正在尝试通过 Amazon SES 发送包含描述事件的 JSON-LD 标记的电子邮件。 JSON-LD 标记似乎没有被 GMail 正确解释。当我发送以下电子邮件时:

我希望事件会按照解释 here. I copy/pasted the HTML content in Email markup tester 出现在我的日历中,并且只收到警告,而嵌入的数据被正确解释。

我做错了什么?

似乎架构是正确的,但需要 register with Google 才能让 Gmail 客户端解释架构。有道理...
