How to delete cookies on auto logout?

Question

we use have some configurations to some user groups (different prices, only some categories etc) and it's all good if the customer logout and login as a different group account, but when it auto logs out after sometime the cookies stay so the customer see in our website the group restrict config as a logged out customer. It's a bit difficult to explain but what I need is to delete the cookies that are created when the customer login when the account logs out by the end of session lifetime.

Is there anything we can do to make this work?

In default Magento, the cookie is deleted once the customer logout. Please check that if you have customised logout action then you must have delete cookie by deleteCookie function of Magento\Framework\Stdlib\Cookie\PhpCookieManager class

Here is the code of default logout action

vendor/magento/module-customer/Controller/Account/Logout.php

public function execute()
{
    $lastCustomerId = $this->session->getId();
    $this->session->logout()->setBeforeAuthUrl($this->_redirect->getRefererUrl())
        ->setLastCustomerId($lastCustomerId);
    if ($this->getCookieManager()->getCookie('mage-cache-sessid')) {
        $metadata = $this->getCookieMetadataFactory()->createCookieMetadata();
        $metadata->setPath('/');
        $this->getCookieManager()->deleteCookie('mage-cache-sessid', $metadata);
    }

    /** @var \Magento\Framework\Controller\Result\Redirect $resultRedirect */
    $resultRedirect = $this->resultRedirectFactory->create();
    $resultRedirect->setPath('*/*/logoutSuccess');
    return $resultRedirect;
}
