Gmail加载项可以始终保持显示状态而不显示电子邮件吗？

Question

Can Gmail Add-ons be defined in a way that a Card or a Widget be displayed before you click on an individual email message? I can't find any examples where this can be done so I'm not sure if this is even possible.

I thought Universal Actions would do the trick, but gmail.universalActions are just actions that does not depend on the current email context.

I'm trying to develop a dashboard mini-app that lives inside of the gmail app, which does not depend on the current email context. It should be always on , and shouldn't be activated when someone clicks on an individual email message.

I would have thought you would need to use a Chrome Extension or something like InboxSDK.

That approach though will limit you to "Gmail in Chrome" only.
