The add_option WordPress function does not add the option - php

Question

I am trying to insert a post/page and then save the post id as an option, but the option is not saving to the database.
I am able to create the page and get the ID of it, but I am unable to save that ID to the options. The class is called at "init" and the constructor is as follows:
class Recipe{
public function __construct(){
$favorites_id = get_option("favoritesid");
if($favorites_id <= 0){
$my_post = array(
'post_title' => 'Favorites',
'post_content' => '',
'post_status' => 'publish',
'post_author' => 1,
'post_type' => 'page'
);
$result_id = wp_insert_post( $my_post );
if($result_id > 0){
add_option("favoritesid", $result_id);
}
}
}

Answer 1

Test the code in the main plugin file: (//use array_push for option)
class Recipe{
public function __construct(){
add_action('init',[$this,'test']);
}
public function test(){
$favorites_id = get_option("favoritesid",[]);
if($favorites_id >= 0){
$my_post = array(
'post_title' => 'this is test',
'post_content' => '',
'post_status' => 'publish',
'post_author' => 1,
'post_type' => 'page'
);
$result= get_page_by_title($my_post['post_title'],ARRAY_A, 'page');
if(is_null($result)) {
$result_id = wp_insert_post( $my_post );
if ( $result_id >= 0 ) {
update_option( "favoritesid", $result_id );
}
}
else return false;
}
}
}
new Recipe;
