create a tkinter menu when using customtkinter

[drbazpython]

Hi all, I'm having a problem (lack of understanding) creating a tkinter menu on the main window whilst defining a customtkinter app.
Can anyone provide some guidance on how to achieve this integration. TIA

Just solved my problem
'
def donothing():
x = 0
app = customtkinter.CTk()
app.geometry("400x580")
app.title("CustomTkinter simple_example.py")
menu_1 = tkinter.Menu(app)
filemenu = tkinter.Menu(menu_1)
filemenu.add_command(label="New", command=donothing)
filemenu.add_command(label="Open", command=donothing)
menu_1.add_cascade(label="File", menu=filemenu)
app.config(menu=menu_1)
