WPML LANGUAGE SELECTOR TO LANGUAGE CODE

Hey guys,
I wanted to change the wpml language selector to language code. but i couldn’t really figure it out.

Couple of issues came along as I followed the instructions on https://kriesi.at/support/topic/wpml-language-selector-in-text-format/#post-524326

1. I don’t want a dropdown menu. I want DE | EN | FR next to each other

add_action('after_setup_theme','avia_remove_main_menu_flags');
function avia_remove_main_menu_flags(){
	remove_filter( 'wp_nav_menu_items', 'avia_append_lang_flags', 20, 2 );
	remove_filter( 'avf_fallback_menu_items', 'avia_append_lang_flags', 20, 2 );
	remove_action( 'avia_meta_header', 'avia_wpml_language_switch', 10);
}

add_action('avia_meta_header', 'add_custom_content_to_header');
function add_custom_content_to_header() {
        do_action('icl_language_selector');
}
