Why does it say "Sign in with your work account" on a Bark Phone?

There's no need to worry that it says "work email." When opening a Google app like the Play Store for the first time, Google asks your kid to sign in with this automated message. 

If your child has a Gmail, it can sign into the Bark Phone on this screen, as long as it's an "unsupervised" account (learn more).
