The first is setting a Readcookie.php controller in the app/code/Mageplaza/HelloWorld/Controller/Cookie. The Readcookie.php contains the following content:

<?php
namespace Mageplaza\HelloWorld\Controller\Cookie;
class Readcookie extends \Magento\Framework\App\Action\Action
{
/**
* @var \Magento\Framework\Stdlib\CookieManagerInterface
*/
protected $_cookieManager;
/**
* @param \Magento\Framework\App\Action\Context $context
* @param \Magento\Framework\Stdlib\CookieManagerInterface $cookieManager
*/
public function __construct(
     \Magento\Framework\App\Action\Context $context,
     \Magento\Framework\Stdlib\CookieManagerInterface $cookieManager
)
{
     $this->_cookieManager = $cookieManager;
     parent::__construct($context);
}
public function execute()
{
     $cookieValue = $this->_cookieManager->getCookie(\Mageplaza\HelloWorld\Controller\Cookie\Addcookie::COOKIE_NAME);
     echo($cookieValue);
}
}

Create the Deletecookie controller in the app/code/Mageplaza/HelloWorld/Controller/Cookie with the following content:

<?php
namespace Mageplaza\HelloWorld\Controller\Cookie;
class Deletecookie extends \Magento\Framework\App\Action\Action
{
/**
* @var \Magento\Framework\Stdlib\CookieManagerInterface
*/
protected $_cookieManager;
/**
* @param \Magento\Framework\App\Action\Context $context
* @param \Magento\Framework\Stdlib\CookieManagerInterface $cookieManager
*/
public function __construct(
     \Magento\Framework\App\Action\Context $context,
     \Magento\Framework\Stdlib\CookieManagerInterface $cookieManager
)
{
     $this->_cookieManager = $cookieManager;
     parent::__construct($context);
}
public function execute()
{
     $this->_cookieManager->deleteCookie(
         \Mageplaza\HelloWorld\Controller\Cookie\Addcookie::COOKIE_NAME
     );
     echo('DELETED');
}
}

And now, you can enable the cookie on your Magento 2 store. If you have any trouble in tracking the topic, leave a comment to ask for the help. Good luck to you!
