When you add a template to Elementor page, you can select editor mode for template

But when you access editor for container or section block models of header and footer are loaded on editor

This code is designed to work with Elementor Pro, a popular WordPress page builder plugin. It aims to conditionally remove the header and footer from specific Elementor templates.
Uses reflectionClass to access the private locations queue property of the $location_manager object and remove the header and footer items
