You could probably do it easier through SideQuest, as it lists the apps installed, then you just select the app, click on it and choose to uninstall. I'm not sure if it will automatically reinstall itself later though, such as after an update.
Could someone try this and let me know if it works? I don't want to be stuck with a device that's not safe for kids and nothing to do with it.
