When trying to view schedules for accounts set as Google Workspace administrators, if the schedules for all members within Google Workspace are displayed, you can resolve this by following these steps on the Google Workspace administrator's account.

Click on the team icon at the top right of the screen > Team settings > Personal settings > Shared calendars.
