Answer 1

We have to add this code in our Namespace/Modulename/Model/ in file.php

 public function isActive($storeId = null)
    {
        $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
        $customerSession = $objectManager->get('Magento\Customer\Model\Session');
        $customerGroupId = $customerSession->getCustomerGroupId();
        if ($customerGroupId != 4) {
            return false;
        }
        return (bool)(int)$this->getConfigData('active', $storeId);
    }
