Magento 2.3 color swatches with related products & upsell products?

Question

I have added color swatches with related products using this code:

<?php 

   if($_item->getTypeId() == \Magento\ConfigurableProduct\Model\Product\Type\Configurable::TYPE_CODE){

   $swatchBlock = $this->getLayout()->createBlock("Magento\Swatches\Block\Product\Renderer\Listing\Configurable")->setTemplate("Magento_Swatches::product/listing/renderer.phtml");
   echo $swatchBlock->setProduct($_item)->toHtml();                           
 }

?>

It is showing swatches fine but when I am clicking on color swatches then product image is not changing.I want to changed product image as well product listing page.

How can I do this?
