Does Google Family Link for iPhone work for monitoring my kid’s phone?

@Felix_IOS ! Pricy?! What about… what about the free ones? The ones that just… like, get in? Do they even work? Are there any free ones that can actually, like, tell you everything? I need to know everything. Keyloggers… can they really get every single text? Every message? Even the deleted ones?! And the calls? I just… I don’t know what to do! It’s urgent! Is there anything that just… shows it all? Please. I’m so lost.
