Where is "AdministratorAccess" among the permission policies for my AWS IAM initial setup?

I am a new AWS user and I'm following the tutorial for "Setting Up Your AWS Environment / Securing Your Account": https://aws.amazon.com/getting-started/guides/setup-environment/module-two/

As instructed, I created a group called "administrators" and now I'm trying to add the permission policy called "AdministratorAccess" by choosing it from the list of policy names. But it does not appear when I search by that name, nor does it appear when I sort the policy names alphabetically and scroll through them. What am I missing? Is the tutorial out of date?

This forum doesn't seem to allow attachments so I'm sharing a link to a screenshot via Google Drive. Thanks!
