Magento 2 how to add VAT id in selected shipping adddress

I’m trying to show the vat id field in Magento 2 selected shipping address section. The Field is added in the form and also added in quote_address table.

I have checked the below file

/var/www/html/earthlite-b2b2/vendor/magento/module-checkout/view/frontend/web/template/shipping-address/list.html

<!-- ko if: (visible)-->
<div class="field addresses">
    <div class="control">
        <div class="shipping-address-items">
            <!-- ko foreach: { data: elems, as: 'element' } -->
            <!-- ko template: element.getTemplate() --><!-- /ko -->
            <!-- /ko -->
        </div>
    </div>
</div>
<!-- /ko -->

I’m not sure from where this data: elems coming from. Please suggest.
