не могу понять, как мне обратиться к координатам в canvas.create_text для их дальнейшего изменения в отдельной функции def change_coord()

window = Tk()
window.title("Watermarking App")

    canvas = Canvas(bg="white", width=1200, height=1200)
    canvas.pack(expand=True)
    image = ImageTk.PhotoImage(Image.open(f"{file_path}"))
    canvas.create_image(0, 0, anchor=NW, image=image)


def font_changed(font):
    label["font"] = font


def save_file():
    canvas.postscript(file="photo.ps", colormode="color")
    img = Image.open("photo.ps")
    img.save("photo.png", "png")


def select_font():
    window.tk.call("tk", "fontchooser", "configure", "-font", label["font"], "-command", window.register(font_changed))

def draw_text():
    text = label["text"]
    font = label["font"]
    canvas.create_text(100, 210, text=f"{text}", font=f"{font}", fill="black")


def write_mark():
    label["text"] = editor.get("1.0", "end")


def change_coord():
    pass
