I'm making a Wordpress theme that generate placeholder menus using the theme support "starter content". I read the documentation and is very vague: https://make.wordpress.org/core/2016/11/30/starter-content-for-themes-in-4-7/.

I want in my theme generate menus and them put images in each menu item using the plugin [Menu Image][1]. But I can't find a hook that executes after starter content generation and executes only once. The hooks I use the content is basically in customizer changeset and I can't access them using the normal the Nav Menu API of WordPress. 

What I can do in this case. Someone have some idea about it? Thanks!
