How to change page url in WordPress?

Question

WordPress

Good afternoon!
I can't write a function that changes the page name in WordPress from "page-name" to "alternate-page-name"...
Here's what I've done so far (doesn't work):

function true_add_html_on_pages() {
  global $wp_rewrite;
 
  if ( $wp_rewrite->get_page_permastruct() == 'page-name' ) {

    $wp_rewrite->page_structure = 'alternate-page-name';

    $wp_rewrite->flush_rules();
  }
}
 
add_action('init', 'true_add_html_on_pages', -1);

Tell the task in full: in what cases and why you need to change.
The solution you provided is a bit of an incomprehensible solution. Will be called each time the page is generated. The first time the name has changed, and then it will work in idle.
