SwiftUI Toolbar back button on macOS

I have a layout similar to Music or Podcasts, where I have a sidebar and a grid content area. When clicking on one of the items in the grid I want to open a full screen detail view just like Music does. My question is: How can I display a back button in the toolbar? I only figured out how to add buttons to the trailing side of the toolbar. Is this even possible in pure SwiftUI?

 
Code Block
.toolbar {
            Button(action: showSearch) {
                Label("Add Game", systemImage: "plus")
            }
        }

Well, it wasn't so hard after all! The question that remains is, how to most efficiently display a detail view on top of the view.

Code Block  .toolbar {
            ToolbarItem(placement: ToolbarItemPlacement.navigation) {
                Button(action: goBack) {
                    Label("Back", systemImage: "chevron.left")
                }
            }
        }


How to place the toolbar item to right side of the tool bar, not the left of trailing side?
