New Outook app -How to have separate window for calendar?

I’m using the beta for the Microsoft’s new Outlook app. One thing that I miss from the old built-in Win11 apps is that Mail and Calendar were separate apps and were each in their own window. I found it easier to switch back and forth between email and my calendar when they were in their own window. But with the new Outlook, they’re both in the same window. Is there any way to get email and calendar in their own windows at the same time?
