WooCommerce! Auto add 4 items to cart how?

Question

WooCommerce

Help with WooCommerce! Automatic addition of 4 items to the cart. Experience in development 0. I'm doing it for the first time, so it's a bit tight. I found this code in the open spaces, which completely suits me, but I can’t make it so that 4 DIFFERENT products with DIFFERENT IDs are added at the same time. Help me please!

/**
 * Add another product depending on the cart total
 */
add_action( 'template_redirect', 'add_product_to_cart' );
function add_product_to_cart() {
  if ( ! is_admin() ) {
    global $woocommerce;
    $product_id = 772; //replace with your product id
    $found = false;
    $cart_total = 1; //replace with your cart total needed to add above item

    if( $woocommerce->cart->total >= $cart_total ) {
      //check if product already in cart
      if ( sizeof( $woocommerce->cart->get_cart() ) > 0 ) {
        foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
          $_product = $values['data'];
          if ( $_product->get_id() == $product_id )
            $found = true;
        }
        // if product not found, add it
        if ( ! $found )
          $woocommerce->cart->add_to_cart( $product_id );
      } else {
        // if no products in cart, add it
        $woocommerce->cart->add_to_cart( $product_id );
      }
    }
  }
}

add_action( 'template_redirect', 'add_product_to_cart' );
function add_product_to_cart() {
  if ( ! is_admin() ) {
    $articles = array(157,158,159,160);
    $found = false;

    // check if product already in cart
    if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
      foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
        $_product = $values['data'];

        if (($key = array_search($_product->id, $articles)) !== false)
          unset($articles[$key]);
      }

      // if product not found, add it
      if ( count($articles) > 0 ) {
        foreach ($articles as $article) {
          WC()->cart->add_to_cart($article);
        }
      }
    } else {
      // if no products in cart, add it
      foreach ($articles as $article) {
        WC()->cart->add_to_cart( $article );
      }
    }
  }
