Style.css file in WordPress child theme doesn’t work

I am using for the first time a child theme on WordPress and I noticed that despite having inserted the customizations in the style.css of the child they are not actually visible in the front-end.

In the child’s functions.php the content is this:

function kerge_child_theme_enqueue_styles() {

$parent_style = 'parent-style';

wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css' );
wp_enqueue_style( 'child-style',
get_stylesheet_directory_uri() . '/style.css',
array( $parent_style ),
wp_get_theme()->get('Version')
);
}
add_action( 'wp_enqueue_scripts', 'kerge_child_theme_enqueue_styles' );

The child theme is up and running.

Some suggestions?
