How to send comment notification message to website admin and post Author using functions.php?

Question

My question is "How to send comment notification to website admin and also post Author?"... In Wordpress default function is "Post author received a comment notification message when user add any comments" but my requirement is totally different. In post - Post Author and website admin only comment (communicate) each other. As per WordPress default notification, Post Auther received the notification but when Auther reply or any comments on the post - Website Admin not received any notification messages.

I am using functions.php and my code is,

function se_comment_moderation_recipients( $emails, $comment_id ) {

    $emails = array( get_option( 'admin_email' ) );

    return $emails;
}
add_filter( 'comment_moderation_recipients', 'se_comment_moderation_recipients', 11, 2 );
add_filter( 'comment_notification_recipients', 'se_comment_moderation_recipients', 11, 2 );

As per my above code, Admin only received but I need If admin reply any comments to post, that particular author received some notification message - If Post author reply or comments any, admin received an alert message.

I am using Multiple user comment notification, this below code is almost covered my requirement.

add_filter('comment_notification_recipients', 'override_comment_notice_repicient', 10, 2);
    function override_comment_notice_repicient($emails, $comment_id) {  
        $admins = get_users( array(
            'role__in'     => array('administrator'),
        ) );
        foreach ( $admins as $user ) {
            $emails[] =  $user->user_email;
        }
        return ($emails);
    }
