recaptcha: wrong instanceof check in Request class (recaptcha hook is not working, ERROR in log)

[gitrequests]

Error in core/components/formit/src/FormIt/Request.php line 85

if (!empty($this->reCaptcha) && $this->reCaptcha instanceof Recaptcha) {
                $this->reCaptcha->render($this->config);

If I understood correctly, $ this-> reCaptcha should be instanceof RecaptchaService (or FormItReCaptcha).
The render method is also in the RecaptchaService class.
Moreover, there is no Sterc\FormIt\Service\Recaptcha class. There is only a Sterc\FormIt\Hook\Recaptcha class.

From error log:
(ERROR @ /var/www/core/components/formit/src/FormIt/Request.php : 88) [FormIt] Could not load FormItReCaptcha service class.

Is the recaptcha hook working correctly?
