## Discussion

Discussion On macOS, accessory bars are in a section below the title bar and toolbar area of the window. Each separate identifier will correspond to a separate accessory bar that is added to this area. Use a custom placement to control the appearance of the containing bar for items using a custom ToolbarItemPlacement with the same identifier. private let favoritesBarID = "com.example.favoritesBar" extension ToolbarItemPlacement {     static let favoritesBar = accessoryBar(id: favoritesBarID) } extension ToolbarPlacement {     static let favoritesBar = accessoryBar(id: favoritesBarID) } ... BrowserView()     .toolbar {         ToolbarItem(placement: .favoritesBar) {             FavoritesBar()         }     }     .toolbar(.hidden, for: .favoritesBar)
