Orange dot on app that does not use microphone.

Developing an app that I currently distribute through TestFlight. The app has the orange dot next to the icon, indicating that the app is using the microphone. However the app does nothing with the microphone, audio, camera and never asks to use it. It's written SwiftUI.

Under Settings->Privacy -> Microphone the app is not listed either and hence nothing to turn off/on.

Force killing the app or/and rebooting the phone does not make a difference. Dot still there.

Seeing this on both IOS 14.3 and 14.4, not sure of other versions and not exactly sure when this started as we just noticed it today.

Any idea whats going on here or how I can debug this further?
