WooCommerce: Own sort/order dropdown (FacetWP)

I want to replace the WooCommerce ordering with the FacetWP sort facet. To do so, I'm using the output hook facetwp_sort_options: https://facetwp.com/documentation/developers/output/facetwp_sort_options/

I have already replaced the order dropdown but the WooCommerce order options are missing.

For now I've only managed to add order by price:

add_filter( 'facetwp_sort_options', function( $options, $params ) {

    $options['price_asc'] = array(
        'label' => 'Price: low to high',
        'query_args' => array(
            'meta_key' => '_price',
            'orderby' => 'meta_value_num',
            'order' => 'ASC'
         )
    );

    $options['price_desc'] = array(
        'label' => 'Price: high to low',
        'query_args' => array(
            'meta_key' => '_price',
            'orderby' => 'meta_value_num',
            'order' => 'DESC'
         )
    );
    return $options;

But how can I add the rest of the WooCommerce order options. Is there any list of meta fields I could use?

I need to add the following order options:

• default order
• Sort by popularity
• Sort by average rating

Edit: Removed the option for sale products (figured it out myself)

Got it from this site

Maybe helpfull:

add_filter( 'facetwp_sort_options', function( $options, $params ) {
unset( $options['date_asc'] );
unset( $options['title_asc'] );
unset( $options['title_desc'] );
$options['default']['label'] = 'Standaard sortering';
$options['date_desc']['label'] = 'Sorteren op nieuwste';

$options['popularity_new'] = [
    'label' => 'Sorteer op populariteit',
    'query_args' => [
        'orderby' => 'post_views',
        'order' => 'DESC',
    ]
];
$options['price_asc'] = [
    'label' => 'Sorteer op prijs: laag naar hoog',
    'query_args' => [
        'orderby' => 'meta_value_num',
        'meta_key' => '_price',
        'order' => 'ASC',
    ]
];
$options['price_desc'] = [
    'label' => 'Sorteer op prijs: hoog naar laag',
    'query_args' => [
        'orderby' => 'meta_value_num',
        'meta_key' => '_price',
        'order' => 'DESC',
    ]
];

return $options;
}, 10, 2 );
