How to link Gutenberg Gallery images To Media file automatically?

Finally by luck i found the answer by @Tomas

function gallery_template_to_posts() {
    $post_type_object = get_post_type_object( 'post' );
    $post_type_object->template = array(
        array( 'core/gallery', array(
            'linkTo' => 'media',
        ) ),
    );
}
add_action( 'init', 'gallery_template_to_posts' );
