TTK 按钮 - 如何使其处于“突出显示”状态？

Question

below a simple code, it's just a button widget placed in a window:

import tkinter as tk
from tkinter import ttk

class MainWindow:
    def __init__(self):
        self.parent=tk.Tk()
        self.parent.geometry("494x410+370+100")
        self.parent.title("Test")

        Button = ttk.Button(self.parent, text="My Button", command=self.DoNothing)
        Button.place(x=16, y=16)

        self.parent.mainloop()
    
    def DoNothing(self):
        pass

if __name__=="__main__":
    app=MainWindow()

is it possible to put this button in "highlighted" state? I mean, is it possibile to change its color like when the mouse cursor stays on it? see the attached image:

in my real software, I have some buttons. all of them open a different menu and when I'm working in one of them, I would very like to remember in which menu I am. to do that I thought to put the button in "highlighted" state and come back to the original one when I click on another button (when I change the menu).

if it is not possible, is there the possibility to change the button colors to make it like when it is in "highlighted" state?

import tkinter as tk


class MainWindow:
    def __init__(self):
        def hover_on(e, color):
            Button['activebackground'] = color

        def hover_off(e):
            Button['activebackground'] = self.default_color

        self.parent = tk.Tk()
        self.parent.geometry("494x410+370+100")
        self.parent.title("Test")

        Button = tk.Button(self.parent, text="My Button", command=self.DoNothing)
        Button.place(x=16, y=16)
        self.default_color = Button['background']

        Button.bind('<Enter>', lambda e: hover_on(e, 'red'))
        Button.bind('<Leave>', lambda e: hover_off(e))

        self.parent.mainloop()

    def DoNothing(self):
        pass


if __name__ == "__main__":
    app = MainWindow()
