Custom Order Delivery State Transition

Hi,
I have a question regarding “Order Delivery State Transition” as described here.
https://docs.shopware.com/en/shopware-platform-dev-en/admin-api-guide/action-routesWe want to implement a new OrderDeliveryState called “pickup” via a plugin.
But it seems like this is not easily possible because the class \Core\Checkout\Order\Aggregate\OrderDelivery\OrderDeliveryStates is defined as final.
Any ideas how to implement this?

Hey @logTom,

Have you found a solution? I have a similar problem and am looking for a solution.
