I want to insert my image into the button, but I get an error when there is a Users element in my image path. is it possible to prescribe the path in some other way so that there are no errors?

from kivymd.app import MDApp
from kivymd.uix.label import MDLabel
from kivymd.uix.button import MDRectangleFlatButton
from kivymd.uix.gridlayout import MDGridLayout

class TestApp(MDApp):
    def build(self):
        layout = MDGridLayout(spacing=30, cols = 3, padding = 200)
        btn1 = MDRectangleFlatButton(text="", icon="C:UsersAlenaDesktopicon")
        btn2 = MDRectangleFlatButton(text="")
        btn3 = MDRectangleFlatButton(text="")
        layout.add_widget(btn1)
        layout.add_widget(btn2)
        layout.add_widget(btn3)
        return layout
TestApp().run()

also, my images are in the same folder as my project

thank you all in advance for your help
