Bundle Add to cart code

Hi i’m trying to add a bundle to a cart but I can’t figure out what is the right config or hooks that I will use.

I’m using gravity form multi step and woocommerce product bundle in which users can build a bundle step by step.

function pre_submission_handler( $form ) {
    
global $woocommerce;
$bundle_id_post = $_POST['input_2']; // bundle id
$bundleproducts = $_POST['input_13']; //products on the bundle
    
if (isset($bundle_id_post)) {
    $bundle_id = wc_get_product($bundle_id_post);
        if ($bundle_id->is_type('bundle')) {
     $bpContainer = array();
     if(!empty($bundleproducts)) {
     foreach ($bundleproducts as $bp => $b) {
       $bpContainer[ $bp ] = array();
       $bpContainer[ $bp ][ 'product_id' ] = $b;
       $bpContainer[ $bp ][ 'quantity' ] = 1;
       $bpContainer[$bp]['variation_id'] = '';
       $bpContainer[$bp]['attributes'] = array();
    }
}
            
    $cart_item_data = (array) apply_filters( 'woocommerce_add_cart_item_data', $cart_item_data, $bundle_id_post, '', 1 );
   $added = WC_PB()->cart->add_bundle_to_cart( $bundle_id_post, 1, $cart_item_data );
   //$added_to_cart = WC()->cart->add_to_cart( $bundle_id, 1, 0, array(), $cart_item_data );
    print_r($added);
    // print_r($cart_item_data);
    wp_enqueue_script('wc-add-to-cart-bundle');
    }
    } 
    
}

add_action( 'gform_pre_submission', 'pre_submission_handler' );
