WordPress Elementor and/or Pages

Dear all,

I just started working with wordpress and really like the elementor application. But how can I combine the elementor app with the “Pages” and “Post” in the WordPress dashboard? I have used elementor for building my whole site. When I want to use the options possible within Post or Pages, it looks like the page is getting ‘refreshed’.

Like to hear.
