We have developed an accessory that supports Find My. When using the Find My app to set it up, it occasionally gets stuck at the final " setting up"" interface. The app just stays like that. We would like to know what could cause this situation and how to resolve it. Thanks a lot.

find my在添加配件是，持续一直卡在“即将完成设置”这一步.这是由于什么原因呢？而且一直保持很长时间，也不会退出，也不会提示任何错误信息。

The Nearby Interaction Accessory Protocol Specification defines a lightweight, transport-agnostic, and application-level protocol that facilitates configuring, starting, and maintaining an Ultra Wideband (UWB) ranging session between an accessory and an Apple device. **An app on a supported UWBenabled Apple device is required in order to allow users to set up, configure, and use their accessories. Does this app need us to develop? Can I use the Find My app to add my accessories and use the UWB high-precision lookup feature?
