How to modify VSCode Activity Bar

Question

I'm customizing VSCode and I need to modify Activity Bar, removing some icon and add one more icon to open extension which is now triggered by keyboard shortcut.

Does anybody have idea how to modify VSCode source code to accomplish that?

Is there any document helping me understand the source code of VSCode?

Any clue will be highly appreciated!

You can right click on the activity bar and select which activity you wish to have in the activity bar.
