PyQt - Connect QAction to function

I am using a TrayIcon, I have added a "Exit" QAction, and now, I want to execute a certain function when clicking Exit in the TrayIcon menu. Here is the code I have :

class TrayIcon(QSystemTrayIcon):
    """
    Displays a system tray icon
    """

    def __init__(self, interface: Interface) -> None:
        """
        Constructor
        :param interface: Interface to show when the tray icon is clicked
        """
        super().__init__(QIcon(resource_filename("ezstorage.resources.img.tray_icon", "folder.png")))
        self.interface = interface
        self.setVisible(True)
        self.show()
        self.activated.connect(self.clicked)
        menu = QMenu()
        action = QAction("Exit")
        menu.addAction(action)
        self.setContextMenu(menu)
