Referral Link Shortcode

I was able to make a custom shortcode using this:

<?php
if (!defined('ABSPATH')) {
    exit;
}
$user_id = get_current_user_id();
$user = new WP_User($user_id);
$referral_url_by_userid = 'id' === $settings['referal_link'] ? true : false;
$referral_url = add_query_arg($referral->referral_handel, $user->ID, wc_get_page_permalink('myaccount'));
if ($referral_url_by_userid) {
    $referral_url = add_query_arg($referral->referral_handel, $user->ID, wc_get_page_permalink('myaccount'));
}
?>
<span>
    <?php _e('Your referral URL is:', 'woo-wallet'); ?>
    <input type="text" readonly="" id="referral_url" value="<?php echo $referral_url; ?>" />
    <div class="referral-tooltip">
        <button onclick="referralTooltip()" onmouseout="referralTooltipOutFunc()">
            <span class="referral-tooltiptext" id="referral_tooltip"><?php _e('Copy to clipboard', 'woo-wallet'); ?></span>
            <?php _e('Copy', 'woo-wallet'); ?>
        </button>
    </div>
</span>

But the displayed link is
https://mywebsite.com/my-account/?=1

but it should be
https://mywebsite.com/my-account/?wwref=1

It is missing wwref=
What did i do wrong here?

Thanks

Please use updated code.

if (!defined('ABSPATH')) {
    exit;
}
$user_id = get_current_user_id();
$user = new WP_User($user_id);
$settings = get_option('woo_wallet_referrals_settings');
$referral_url_by_userid = 'id' === $settings['referal_link'] ? true : false;
$referral_url = add_query_arg(apply_filters('woo_wallet_referral_handel', 'wwref'), $user->ID, wc_get_page_permalink('myaccount'));
if ($referral_url_by_userid) {
    $referral_url = add_query_arg(apply_filters('woo_wallet_referral_handel', 'wwref'), $user->ID, wc_get_page_permalink('myaccount'));
}
?>
<span>
    <?php _e('Your referral URL is:', 'woo-wallet'); ?>
    <input type="text" readonly="" id="referral_url" value="<?php echo $referral_url; ?>" />
    <div class="referral-tooltip">
        <button onclick="referralTooltip()" onmouseout="referralTooltipOutFunc()">
            <span class="referral-tooltiptext" id="referral_tooltip"><?php _e('Copy to clipboard', 'woo-wallet'); ?></span>
            <?php _e('Copy', 'woo-wallet'); ?>
        </button>
    </div>
</span>
