Using wpcf7_feedback_response to output html in the response?

I am trying to output a hidden iFrame that will load in the AJAX response after submitting the form. It just outputs it as a string currently. Is this possible to do any other way?

add_filter('wpcf7_feedback_response', function($response, $result) {
    $iframe_url = "https://software.loks.com/handler239" . "email=" . urlencode($_POST['email']) . "&company=" . urlencode($_POST['company']) . "&phone=" . urlencode($_POST['phone']);

    $iframe_html = '<iframe src="' . $iframe_url . '" width="1" height="1" style="display:none;"></iframe>';
    $response['message'] = $iframe_html;

    return $response;
}, 10, 2);
