How to get the final amount (purchase amount + shipping amount) in OpenCart?

Question

opencart

I'm trying to find a solution in a method in the ControllerCheckoutCart and ControllerCheckoutSimpleCheckoutCart class (because it costs simplecheckout), but I can't find it yet.
I already got the total amount of the purchase via $order_products = $this->model_account_order->getOrderProducts($order_id);
But I can't figure out how to get the final amount including shipping costs.

If you are working with a standard cart, then look somewhere here prntscr.com/cw96na in the ControllerCheckoutCart class, in this section of the code the cost is being calculated, there is a similar functionality in the ControllerCheckoutConfirm and maybe somewhere else.
In general, it is possible to change the settings in the "Take into account in the order" section.
