How does Fresh KDS get the dining options from the API?

For the example in the photo, that customer is using Square POS (Register) to enter the orders, and then they’re displayed on Fresh KDS with the for here/to go delivery option. I’m assuming they’re using the Orders API like I am, but maybe not? Is there another place I need to be listening for to get that data?

Also, does this have an ETA for when it will be added to the Orders API? Seems like a simple add, just need to pass it along. Based on the other forum posts, now that the orders conversion is done, it should be doable, right?
