Create a fulfillment with FulfillmentOrders

[MaksBrainiac]

My print on-demand app has registered a fulfillment service (fulfillment_orders_opt_in = true).

I can see created fulfillment_orders assigned to my Fulfillment Service location for new orders .

"supported_actions" are ["request_fulfillment", "create_fulfillment", "hold"]

but call to fulfillmentCreateV2 responds with "Cannot create fulfillment for the fulfillment order."

Why create_fulfillment is in supported_actions if API does not allow use it? Is it possible to create a fulfillment without request_fulfillment API call or Request Fulfillment made by the merchant?

Looks like it is possible, but the app needs additional permissions:

read_third_party_fulfillment_orders, write_third_party_fulfillment_orders
