Home panel - add button behavior

[Vike]

Hello, just adding a simple panel to the clientarea homepage using the code from the WHMCS docs. Is there any way to declare that when the panel button is pressed that it can open up in a new window/tab/etc? Below is the sample code from the WHMCS docs.

<?php

use WHMCS\View\Menu\Item;

add_hook('ClientAreaHomepagePanels', 1, function (Item $homePagePanels)
{
    $thankYouMessage = <<<EOT
<p>Thanks for beta testing our latest offerings! To show our appreciation we'd
like to provide next month of service <strong>on the house</strong>.</p>
EOT;

    // Add a homepage panel with a link to a free month promo and mode it to the
    // front of the panel list.
    $homePagePanels->addChild('thanks', array(
        'label' => 'Thanks for the help!',
        'icon' => 'fa-thumbs-up',
        'order' => 20,
        'extras' => array(
            'color' => 'gold',
            'btn-link' => 'https://example.org/free-month-promo',
            'btn-text' => 'Redeem Your Free Month',
            'btn-icon' => 'fa-arrow-right',
        ),
        'bodyHtml' => $thankYouMessage,
        'footerHtml' => 'Act fast! This offer expires soon!',
    ));
});
