show low in stock products - wordpress

Question

for my website, I need a page to display the low in stock products only, as same as choosing to display only top rated, sales, recent products.
I found a code to display the out of stock .. so I just replace "outofstock" value to "lowinstock", but that doesn't work, it shows all of the products
add_shortcode( 'out_of_stock_products', 'bbloomer_out_of_stock_products_shortcode' );
function bbloomer_out_of_stock_products_shortcode() {
$args = array(
'post_type' => 'product',
'posts_per_page' => -1,
'post_status' => 'publish',
'meta_query' => array(
array(
'key' => '_stock_status',
'value' => 'outofstock',
)
),
'fields' => 'ids',
);
$product_ids = get_posts( $args );
$product_ids = implode( ",", $product_ids );
return do_shortcode("[products ids='$product_ids']");
}
Do you have any solutions for this??
I appreciate your help

You could filter the product IDs and check if the amount in stock is lower than the low stock threshold but greater than zero (out of stock).
add_shortcode( 'out_of_stock_products', 'bbloomer_out_of_stock_products_shortcode' );
function bbloomer_out_of_stock_products_shortcode() {
$args = array(
'post_type' => 'product',
'posts_per_page' => -1,
'post_status' => 'publish',
'fields' => 'ids',
);
$product_ids = get_posts( $args );
foreach ( $product_ids as $key => $product_id ) {
if ( $product = wc_get_product( $product_id ) ) {
$stock = $product->get_stock_quantity();
$low_stock_amount = $product->get_low_stock_amount();
if ( !empty( $stock ) && !empty( $low_stock_amount ) ) {
if ( $stock > $low_stock_amount || $stock < 1 ) {
unset( $product_ids[$key] );
}
} else { //Not enough stock data
unset( $product_ids[$key] );
}
}
}
$product_ids = implode( ",", $product_ids );
return do_shortcode("[products ids='$product_ids']");
}
