Base Currency Grand Total is already showing on the payment & review page on checkout.
[![enter image description here][1]][1]

HTML responsible to show base Currency Grand Total is:

`/vendor/magento/module-tax/view/frontend/web/template/checkout/summary/grand-total.html`

Code:
```
<!-- ko if: isBaseGrandTotalDisplayNeeded() && isDisplayed() -->
<tr class="totals charge" style="border-top: 1px solid;">
    <th class="mark" data-bind="i18n: basicCurrencyMessage" scope="row" style="font-weight: bold;color: #A82682;"></th>
    <td class="amount">
        <span class="price" data-bind="text: getBaseValue(), attr: {'data-th': basicCurrencyMessage}" style="font-weight: bold;color: #A82682;"></span>
    </td>
</tr>
<!-- /ko -->
```

I want to show the same Base Currency Grand Total on Shipping Page, but it is not working.

I have added the same code to this file but it is not showing the base Currency Grand Total.

Code:
```
<span class="mark" data-bind="i18n: basicCurrencyMessage" scope="" style="font-weight: bold;color: #A82682;"></span>
<span class="price" data-bind="text: getBaseValue(), attr: {'data-th': basicCurrencyMessage}" style="font-weight: bold;color: #A82682;"></span>
```

File:

`vendor/magento/module-checkout/view/frontend/web/template/estimation.html`

Note: it is bad practice to update files inside the vendor folder. I will override these files after testing.
