Several times over the last week, I've noticed a green dot when unlocking my phone. It goes away shortly after the unlock completes. I understand this means an app is using my camera while the device is locked. I've enabled app activity recording and inspected the logs following these instructions: https://developer.apple.com/documentation/network/privacy_management/inspecting_app_activity_data
Upon inspection, I'd expect to see an entry with "type": "access" somewhere but there are none. Everything recorded has the type networkAccess only.
Why am I seeing the green dot without any related access logs?
