wp_bootstrap_navwalker / wp_list_pages

I’m using the bootstrap navwalker but it requires targeted menu, I’m trying to use the bootstrap navwalker with the page hierarchy.

So the menu is dynamically generated showing the children of the current page, but styled correctly, you can see my question in more detail here.
