Is it possible to mirror someone's iPhone without them knowing it's being monitored?

My teenage daughter has been super secretive with her phone lately and I’m getting really worried about who she is talking to online. I know there are built-in screen casting features, but from what I’ve read, they always pop up a huge notification or put a colored bubble at the top of the screen when they are active. Does anyone know of a workaround or a quiet method to see what they are doing in real-time without triggering those obvious alerts?

There’s no reliable way to monitor someone’s iPhone silently without violating privacy or laws. Focus on open communication instead.
