有没有办法在tkinter.ttk.Notebook的标签页上添加关闭按钮？

import tkinter as tk
from tkinter import ttk

class ClosableTab(ttk.Frame):
    def __init__(self, parent, text):
        super().__init__(parent)
        
        self.parent = parent
        self.text = text
        
        self.label = ttk.Label(self, text=self.text)
        self.label.pack(side="left", padx=5)
        
        self.close_button = ttk.Button(self, text="x", command=self.close_tab)
        self.close_button.pack(side="left")
        
    def close_tab(self):
        index = self.parent.index(self)
        self.parent.forget(index)

root = tk.Tk()

notebook = ttk.Notebook(root)

tab1 = ClosableTab(notebook, "Tab 1")
notebook.add(tab1, text="Tab 1")

tab2 = ClosableTab(notebook, "Tab 2")
notebook.add(tab2, text="Tab 2")

notebook.pack()

root.mainloop()
