how can i find out if someone downloaded the Calculator hidden app on my s9+?

[Android Central Question]

I bought a samsung s9+ for my daughter and I believe that she has downloaded the Calculator app. The one that hides contacts, sms etc?

So I'm confused on who owns the phone. Is it your S9 or your daughter's? If it's yours and the Google account is yours, you can just look at the Play Store history.
