If you look at the page.php template itself you will see the sidebar isn’t included.
You can put that in hardcode (see the single.php as example).
Or make another template especially to show the sidebar.
Wordpress will let you choose additional templates when making pages through the admin

I think this will require CSS modifications as well. The first step would be to set up a Child Theme: https://codex.wordpress.org/Child_Themes
Then copy the templates you want to modify and put them in your Child Theme folder. You can then safely modify those template files and not worry about those modifications being erased when the theme updates.
