I've added a background downloads extension to my app and added device console logging to every method in the placeholder code created by XCode, and Setting a breakpoint, then installed the app to the phone. When I run the following command: xcrun backgroundassets-debug --app-bundle-id com.myCompany.myApp --device-id 00008110-001E0DDA0AB8801E --simulate --app-update  prompt： Application was updated event was sent for app identifier: (com.myCompany.myApp). But the break point did not enter。Nothing is sent, and there is no log output How do I set breakpoints in the extension for debugging？
