How is it possible to put the WordPress global and classic inline css style into the head?
I do not use the main function wp_head() so I am looking for a programmatically answer.

What I tried so far

add_action('wp_enqueue_scripts', function(){
    wp_enqueue_style('global-styles');
    wp_register_style('global-styles');
});

and

add_action('init', function(){
    wp_enqueue_global_styles();
});

But this does not make sense.

Hope somebody has the answer or can put me in the right direction.
