Make Elementor the default editor

Hi, I need to make elementor default wordpress editor.
In old topics I found the solution but this code https://gist.github.com/heyfletch/7c59d1c0c9c56cbad51ef80290d86df7 gives error

`Uncaught Error: Call to undefined function get_current_screen() in wp-content/themes/hello-theme-child-master/functions.php:30
