Separate logic for guest and logined users

Hi. In First – thanks for greate work.

Say me please (divide), how I can separate time cart expiration for guest (example 10 minuts) and for loginet user (example 24 haurs)

I think in thise file woocommerce-cart-stock-reducer/includes/class-wc-csr-session.php :
somesing like thise:

public function set_session_expiration() {

if(is_user_logged_in()){
		$this->_session_expiring   = time() + intval( apply_filters( 'wc_session_expiring', 60 * 60 * 24) ); // set- MY VALUE
}
else if(!is_user_logged_in())
{
	$this->_session_expiring   = time() + intval( apply_filters( 'wc_session_expiring', 60 * 10) ); // set- MY VALUE 10 minuts
}
ets....
		$this->_session_expiration = time() + intval( apply_filters( 'wc_session_expiration', 60 * 60 * 48 ) ); // 48 Hours.
	}

Its right way?
And I cant understand why in plugin file set values – https://i.imgur.com/UhcREf1.png
