You didn’t mention which docs you were reading.
The Code Editor Theme readme says:
codeeditor_menu_mostrecentposts, defaults totrue, whether to show the “Most recent posts” section within the menu
That means it is coded into the template. The theme doesn’t have a way to configure additional menus, so you’ll need to override the templates, so you can add menu templates, and then configure your menus.
