Languages on Mobile menu

Hello,

I’m trying to put in the right column links language. I’m trying with functions.php of my child theme, right after the registration area.

I have the language code, but I don’t know exactly how to enter the arrays.

The code of WPML is:
<?php do_action('wpml_add_language_selector'); ?>

I spoke with WPML support but do not quite know where to place

And the code of functions is:

add_filter( 'basel_header_configuration', 'basel_custom_header_configuration', 1, 1 );

function basel_custom_header_configuration() {

		return array(
			'container' => array(
				'wrapp-header' => array(
					'logo',
					'widget_area',
					'right-column' => array(
						'header_links',
						'search',
						'wishlist',
						'cart',
						'mobile_icon',
						
					)
					
				)
			),
			'navigation-wrap' => array(
				'container' => array(
					'main_nav'
				)
			)
		);

}

?>

I don’t know how to do that, can you help me?

Thanks!
