Set programmatically image roles

Question

I have that in my backoffice :

and I need that:

This solution does not work for me :

  if($key == 1){
        $prod->addImageToMediaGallery($imgPath, array('image', 'small_image','thumbnail'), false, false);
    }else{
        $prod->addImageToMediaGallery($imgPath, null, false, false);
    }
    $prod->save();

How can I do ?

Thank you

EDIT : my new implementation, but it is not working :

if(!$productFactory) $productFactory=$objectManager->create('Magento\Catalog\Model\ProductFactory');
$product=$productFactory->create()->load($id_product_for_image);
$product->addImageToMediaGallery($tmpName, $is_cover ? array('image', 'thumbnail', 'small_image') : array(), false, false);

I think it is connected to this problem : https://github.com/magento/magento2/issues/34658

Use the Following code to overcome this

/** \Magento\Catalog\Model\ProductFactory $product */
$product = $this->productFactory->create();
foreach ($totalImages as $index => $path) {
   $type = [];
   if ($index == 0) {
       $type = ['image', 'thumbnail', 'small_image'];
   }
   $product->addImageToMediaGallery(
             $path,
             $type,
             false,
             false
   );
}
