The Admin page gives you access to the Analytics administrative features. Click Admin on the bottom-left to open the page.
The Admin page for a Google Analytics 4 property has different options than the Admin page for a Universal Analytics property.
For example, the Property column for the Google Analytics 4 Admin page includes a link for Data Streams, which doesn't appear in the Universal Analytics Admin page.
And in the Universal Analytics Admin page, you have a third column for Views, which are not a feature of Google Analytics 4.
