Is there a reliable facebook activity checker I can use to monitor my teen?

My teenager has been acting pretty secretive lately and I want to make sure they are safe online without completely invading their privacy. I have looked into a few apps but most seem to require root access or just don’t update their features anymore. Could anyone recommend a straightforward tool that actually tracks messaging and friend requests without getting flagged by the platform?

There are no foolproof tools that track messaging or friend requests without risk. Most reliable options require significant access or violate platform policies.
