I am making an extension for github. I already created extension for VSTS.
My goal - write extension that adds some custom tab with own functionality.
Github guide explains that I can create "github app" that will send to my webhook server all changes that I subscribed them. But nothing about new functionality on their site in difference that VSTS.
I installed extensions of other developers that add this custom tab. But they all required installation of chrome extension.
Do I need to develop chrome extension that adds this tab on github.com pages. Or Is there other ways to implement this?
