How to view select a different Reminder List when Sidebar is closed?

In Mojave, you could select a different Reminder list when the sidebar was closed. You could do this by selecting one of the "dots" on the bottom of the window.

How do you do this in the new Reminders introduced in Catalina?

I'm really not a fan of keeping the sidebar open all the time as the Reminders window now takes up much more screen real estate that before.

Thanks!
