Magento 2.4 Sidebar\RemoveItem - afterExecute() must be an instance of Magento\Framework\App\Response\Http - magento2

Question

I have a plugin in my module that was working in Magento 2.3, but after upgrade to 2.4 i am getting the error
TypeError: Argument 2 passed to
..\Plugin\Controller\Checkout\Sidebar\RemoveItemPlugin::afterExecute()
must be an instance of Magento\Framework\App\Response\Http, instance
of Magento\Framework\Controller\Result\Json\Interceptor given
This is the code :
use Magento\Customer\CustomerData\SectionPoolInterface;
use Magento\Framework\Serialize\Serializer\Json;
class RemoveItemPlugin
{
public function __construct(
SectionPoolInterface $sectionPool,
Json $json
) {
$this->sectionPool = $sectionPool;
$this->json = $json;
}
public function afterExecute(
\Magento\Checkout\Controller\Sidebar\RemoveItem $subject,
\Magento\Framework\App\Response\Http $result
): \Magento\Framework\App\Response\Http {
/* Get Cart Items */
$sectionNames = "cart";
$sectionNames = $sectionNames ? array_unique(\explode(',', $sectionNames)) : null;
$forceNewSectionTimestamp = false;
$response = $this->sectionPool->getSectionsData($sectionNames, (bool)$forceNewSectionTimestamp);
/* Prepare Result */
$content = $this->json->unserialize($result->getContent());
$content['cartSection'] = $response;
$content = $this->json->serialize($content);
$result->setContent($content);
return $result;
}
}
I tried the answer in this question :
https://magento.stackexchange.com/questions/351344/magento-2-4-sidebar-removeitem-afterexecute-must-be-an-instance-of-magento-f
but once I change $result to be type resultInterface, I can no longer use $result->getContent() to return the cart json. Is there a way to do this with resultInterface?
