Im using TkinterMapView (https://github.com/TomSchimansky/TkinterMapView) and im trying to store data in a maker when i create it and then access said data when i call a function from it – my code is as follows:

import tkinter
import tkinter.messagebox
from tkintermapview import TkinterMapView
from tkinter import simpledialog

class App(tkinter.Tk):

    APP_NAME = "name.py"
    WIDTH = 800
    HEIGHT = 750

    def __init__(self, *args, **kwargs):
        tkinter.Tk.__init__(self, *args, **kwargs)

#command that im calling from the marker
        def click_command(self, marker):
            self.map_widget.delete_all_marker()
#creating marker
        self.map_widget.set_marker(56.243350, -3.9111328, text="Example_text", marker_color_circle = '#E622C5', command = self.click_command)
