Magento 2.3.2 - Switch Website (store) without going to base URL

Question

I'm using the following code to switch websites.

app/design/frontend/[Vendor]/{Child_theme}/Magento_Store/templates/switch/languages.phtml

<?php
/** @var \Magento\Store\Block\Switcher $block */
$viewModel = $block->getData('view_model');
$websites = $viewModel->getWebsites();
$websiteid = $viewModel->getWebsite()->getWebsiteId();
?>
<div class="switcher store switcher-store" id="switcher-store">
    <strong class="label switcher-label"><span><?php echo __('Choose your Country') ?></span></strong>
    <div class="actions dropdown options switcher-options">
        <?php foreach ($websites as $website): ?>
            <?php if ($websiteid == $website->getId()): ?>
                <div class="action toggle switcher-trigger"
                     role="button"
                     tabindex="0"
                     data-mage-init='{"dropdown":{}}'
                     data-toggle="dropdown"
                     data-trigger-keypress-button="true"
                     id="switcher-store-trigger">
                    <strong>
                        <span class="<?php echo str_replace(' ', '-', $block->escapeHtml($website->getName())) ?>">
                            <strong><a><?php echo $block->escapeHtml($website->getName()) ?></a></strong>
                        </span>
                    </strong>
                </div>
            <?php endif; ?>
        <?php endforeach; ?>
        <ul class="dropdown switcher-dropdown" data-target="dropdown">
            <?php foreach ($websites as $website): ?>
                <?php if (!($websiteid == $website->getId())): ?>
                    <li class="switcher-option view">
                        <span class="flag-icon <?php echo str_replace(' ', '-', $block->escapeHtml($website->getName())) ?>">
                            <a href='<?php echo $website->getDefaultStore()->getBaseUrl() ?>'>
                            <?php echo $block->escapeHtml($website->getName()) ?>
                        </a>
                        </span>
                    </li>
                <?php endif; ?>
            <?php endforeach; ?>
        </ul>
    </div>
</div>

However, when a product page is accessed on a particular website and then the website is switched it goes back to the base url of the website switched to.

For example

Different websites are

• xyz.com/us
• xyz.com/uk
• xyz.com/eu

URL that is accessed is xyz.com/uk/apple.html and say you switch to the US website, it goes to xyz.com/us instead of xyz.com/us/apple.html

How can I get it to switch to the same page but on the other website.

The solution for this is from this question by Daniel

Replace

<a href='<?php echo $website->getDefaultStore()->getBaseUrl() ?>'>
     <?php echo $block->escapeHtml($website->getName()) ?>
</a>

with

<a href='<?php echo $viewModel->getTargetStoreRedirectUrl($website->getDefaultStore()) ?>'>
     <?php echo $block->escapeHtml($website->getName()) ?>
</a>
