❔ Prism: Change view in region - How to add multiple views to region and activate?

Hey, currently I'm developing a WPF application that has a navigation menu on the left (basically a treeview) and a content panel on the right. Whenever I click on a treeview item, the details about that item should be displayed on the right side within the content panel. There are different types of items and each type has a view and a viewmodel. How do I add multiple views to a region and activate one at a time? I added the views like this

            var regionmanager = Container.Resolve<IRegionManager>();
            regionmanager.RegisterViewWithRegion(RegionNames.ContentRegion, typeof(PersonDetails));
            regionmanager.RegisterViewWithRegion(RegionNames.ContentRegion, typeof(Overview));

            var regionmanager = Container.Resolve<IRegionManager>();
            regionmanager.RegisterViewWithRegion(RegionNames.ContentRegion, typeof(PersonDetails));
            regionmanager.RegisterViewWithRegion(RegionNames.ContentRegion, typeof(Overview));

and PersonDetails is showed. When I run

            RegionManager.Regions[RegionNames.ContentRegion].Activate(typeof(Overview));

            RegionManager.Regions[RegionNames.ContentRegion].Activate(typeof(Overview));

I get an error

This RegionManager does not contain a Region with the name

This RegionManager does not contain a Region with the name

When I exchange "RegisterViewWithRegion" by "AddToRegion" I get another exception. What's wrong here?
