Is there an order state change event in Shopware 6?

Orders in Shopware 6 have these states:

<?php declare(strict_types=1);

namespace Shopware\Core\Checkout\Order;

final class OrderStates
{
    public const STATE_MACHINE = 'order.state';
    public const STATE_OPEN = 'open';
    public const STATE_IN_PROGRESS = 'in_progress';
    public const STATE_COMPLETED = 'completed';
    public const STATE_CANCELLED = 'cancelled';
}

Is it possible to subscribe to the state changes? Is there a state change event or could these states be used as events? If yes, how to get the changed state name?
