Please don’t mind, I figured it out.
It must be like this…

<?php
add_action( ‘wp_enqueue_scripts’, ‘my_theme_enqueue_styles’ );
function my_theme_enqueue_styles() {
$parenthandle = ‘parent-style’;
$theme = wp_get_theme();
wp_enqueue_style( $parenthandle, get_template_directory_uri() . ‘/style.css’,
array(), // if the parent theme code has a dependency, copy it to here
$theme->parent()->get(‘Version’)
);
wp_enqueue_style( ‘child-style’, get_stylesheet_uri(),
array( $parenthandle ),
$theme->get(‘Version’)
);
}
