How to get users to install my application, manually initiate fulfillment after creating an order, and display the Request fulfillment button, as shown in the picture https://screenshot.click/17-18-83237-92609.png I refer to the documentation to complete all the fulfillment orders that require them to be assigned to your API fulfillment service location, and the supportedActions section contains’ REQUEST-FULFILLMENT ‘and the requestStatus is’ UNSUBMITTED’, authorizing all relevant permissions, but button is not displayed .
In addition, I tried to request FulfillmentOrderSubmitFulfillmentRequest, but after the request was successful, there was no button displayed. Instead, the order was shipped and its status changed from ‘never shipped’ to ‘in progress’. How can I improve the display of Request fulfillment on the order details page
