Hi,
to generate the list of notifications I use this code, but I need to verify which of the notifications have the status of not read.

if (bp_has_notifications($args)) :

        while (bp_the_notifications()) : bp_the_notification();

            ob_start();
            bp_the_notification_description();
            $title[] = ob_get_contents();
            ob_end_clean();

            ob_start();
            bp_the_notification_time_since();
            $since[] = ob_get_contents();
            ob_end_clean();

        endwhile;

    endif;

How can I get this status?

Thanks.
