我如何获得我点击添加到我创建的每封邮件的主题和正文？

Question

I want to create an add-on similar to Trello. Every time you open a mail, Trello automatically fills in the "Name" and "Description" fields for you. The name here is the "subject" of the mail and the description is the "body" of the mail. I want to achieve the same thing.

[trello-image-example][1] [trello-image-example][2] [my-add-on][3]
Here is my code: https://www.toptal.com/developers/hastebin/pejasapero.php

I get this when I run my code:
