封装为类的tkinter，怎么在类外把信息写到Tkinter的text控件中

import tkinter as tk
from tkinter import scrolledtext


class App:
    def __init__(self, window):
        self.window = window
        self.window.title("main")
        self.window.geometry("600x300")
        self.labelframe()
        self.text_insert()

    def labelframe(self):
        lf = tk.LabelFrame(
            self.window, text="运行信息", font=("微软雅黑", 10, "bold"), padx=10, pady=10
        )
        lf.place(x=20, y=20)

        text = scrolledtext.ScrolledText(lf, height=5, width=65, font=("微软雅黑", 10))
        text.grid()

        self.text = text

    def text_insert(self):
        self.text.insert("end", "Part_1：这是类内写入的信息... \n")


# 怎么在类外把信息写到Tkinter的text控件中
message = "Part_2：这条信息，在类外写入Tkinter text控件"


root = tk.Tk()
app = App(root)
root.mainloop()

root = tk.Tk()

app.change(message)
root.mainloop()
