nitpick: the “where is erica?” is a catchy title for the feature being showcased - which is actually a notification that your child made it to school safely.

When I click on that square it says:

See everyone’s location using the Find My app. And receive alerts when they arrive at their destination or get home. Parents can also get alerts when their child leaves a location, like school.

So the image shows a notification, but it claims to be possible to inspect their location at any time too.
