The following code is working fine to create order programmatically with simple products. How can I write the code to create order with configurable products?

    if (file_exists($  orderFile) && file_exists($  orderItemFile)) {                  $  orderData = $  this->fileCsv->getData($  orderFile);                 $  orderItemData = $  this->fileCsv->getData($  orderItemFile);                  $  this->_resources = \Magento\Framework\App\ObjectManager::getInstance()                     ->get('Magento\Framework\App\ResourceConnection');                  $  connection= $  this->_resources->getConnection();                  $  tableName = $  this->_resources->getTableName('sequence_order_1');                  foreach ($  orderData as $  ordValue) {                      if ($  ordValue[0] != "ORD_ID" && $  ordValue[2] != "ORD_VEC_ID") {                          $  orderData = [                             'currency_id'  => 'USD',                             'email'        => $  ordValue[6],                             'shipping_address' =>[                                 'firstname'    => $  ordValue[14], //address Details                                 'lastname'     => $  ordValue[15],                                 'street' => $  ordValue[16],                                 'city' => $  ordValue[17],                                 'country_id' => $  ordValue[18],                                 'region_id' => $  ordValue[19],                                 'region' => $  ordValue[19],                                 'postcode' => $  ordValue[20],                                 'telephone' => $  ordValue[21],                                 'fax' => $  ordValue[22],                                 'save_in_address_book' => 1                             ]                         ];                         foreach ($  orderItemData as $  oriValue){                              if ($  oriValue[0] != "ORI_ID" && $  oriValue[1] == $  ordValue[0]) {                                  $  sku = $  oriValue[3];                                 $  _product = $  blockInstance->getProductBySku($  sku);                                 $  productId = $  _product->getEntityId();                                  $  productItem[] = ['product_id'=>$  productId,'qty'=>$  oriValue[4],'price'=>$  oriValue[22]];                              }                         }                         $  orderData['items'] = $  productItem;                          $  sql = "ALTER TABLE " . $  tableName .
