[Question]How to place an ElevatedButton

[AngelCard]

Question

I am trying to place an ElevatedButton in the upper right side of a column where it has an image and a text. So I tried to make a row but when I execute the button it doesn't come out where I want it to.

The button should have a 40px margin on the top, left and right side.

Below is a reference image of how it has to look like

But when executing the code it comes out like this ➡.

Code sample

import flet 
from flet import *

def main(page: Page):
    page.title = 'EduConter'
    page.theme_mode = 'LIGHT'
    page.padding = 0
    page.window_maximized = True
    page.window_resizable = False
    page.vertical_alignment = 'Center'
    page.horizontal_alignment = 'Center'
    page = Container(
                    Stack([
                        Image(
                            src='./images/fondoWelcome.jpg'
                        ),
                        Container(
                            Container(
                                Row(
                                    spacing=0,
                                    alignment=MainAxisAlignment.CENTER,
                                    controls=[
