See how the core does it for the backend pages:

magento/magento2/blob/e0ed4bad/app/code/Magento/Security/view/adminhtml/templates/js/init_ajax_session_checker.phtml#L13-L19


<script type="text/x-magento-init">
{
    "*": {
         "securitySessionChecker": <?php /* @escapeNotVerified */ echo $block->getSessionCheckerJson() ?>
    }
}
</script>

<referenceContainer name="before.body.end">
    <block class="Magento\Security\Block\Adminhtml\Js\Checker" name="security.init.ajax.session.checker" template="Magento_Security::js/init_ajax_session_checker.phtml" />
</referenceContainer>
