You can use the existing current customer template variable same as the store you can find the function getFullCustomerObject in the file: vendor/magento/module-customer/Model/EmailNotification.php in this method data are already passing you can modify it as per your preference.

You can refer the emailChanged function in the same file where it call the sendEmailTemplate function and it has the $templateParams params in the 4th Arguments.

So in the template, you can use the variable $customer

{{trans 'If you have not authorized this action, please contact us immediately at <a href="mailto:%store_email">%customer_email</a>' customer_email=$customer.email |raw}}
