add gclid as description

Hi,

I have a form in the bottom of this page (not the button on top), where I send a donation.

My goal is to change Stripe description for something like “Petit Magicien Conversion GAds | gclid=test213test”.

For this, I used this following function (in function.php) :

function stripe_custom_description($description) {
    // Vérifier si le gclid est présent dans l'URL
    if (isset($_GET['gclid']) && !empty($_GET['gclid'])) {
        $gclid = sanitize_text_field($_GET['gclid']);
        // Définir une nouvelle description seulement si le gclid existe
        $description = "Petit Magicien Conversion GAds | gclid=" . $gclid;
    }
    
    // Retourner la description (modifiée ou originale)
    return $description;
}

add_filter('give_payment_gateway_donation_summary', 'stripe_custom_description', 10, 1);

Even though there is a ?gclid=test213test in the URL, the end description in Stripe is not changing.

What can I do to solve this?
