Additionally, to open new window, this code can help you

windowController.contentViewController = tabViewController

The full code is like that i used it in my project:

@objc func openApplicationView(_ sender: Any?) {
    let mainStoryBoard = NSStoryboard(name: "Main", bundle: nil)
    let tabViewController = mainStoryBoard.instantiateController(withIdentifier: "tabView") as? TabViewController
    let windowController = mainStoryBoard.instantiateController(withIdentifier: "secondWindow") as! TabViewWindowController
    windowController.showWindow(self)
    windowController.contentViewController = tabViewController
}

It can helpful if you've closed the mainWindow. So you need to add one windowController and tabViewController(you can use normal view controller) in your own underlying storyboard.

In my side the tabViewController has been extended by NSTabViewController and tab view component has been bound with this class.

Note: I've also added the windowController in my Main.storyboard as a component and identified to use then on coding side.
