WordPress add_setting_section does not recognise custom page - wordpress

Question

I trying to create a custom settings page for my plugin, but I'm unable to make the page display a custom settings page, to make things simple I just want to display the section header.
Here is what I have.
private function add_hooks() {
add_action('admin_menu', array($this,'register_menu'));
add_action("admin_init", array($this,"display_options"));
}
public function register_menu() {
add_menu_page('Feed','API FEED','manage_options','adt-feed',array($this,'include_admin_page'),'dashicons-format-image');
}
public function include_admin_page() {
return include_once( PLUGIN_PATH 'admin/view/config-page.php' );
}
public function display_options()
{
//section name, display name, callback to print description of section, page to which section is attached.
add_settings_section("adt_general_section", "Header Options", array($this, "display_header_options_content"), "adt-feed");
}
public function display_header_options_content() { //THIS NEVER GETS CALLED
echo "PLUGIN HEADER SECTION";
}
and them in my config-page.php i have:
<div class="wrap">
<div id="icon-options-general" class="icon32"></div>
<h1>ADT Feed Options</h1>
<form method="post" action="options.php">
<?php
//add_settings_section callback is displayed here. For every new section we need to call settings_fields.
settings_fields("adt_general_section");
// Add the submit button to serialize the options
submit_button();
?>
</form>
</div>
Using some "die()" calls i manage to find that display_header_options_content never gets called, if i change "adt-feed" for "general" in the add_settings_section, i can see the message: "PLUGIN HEADER SECTION" in the General settings page.
thanks in advance for any help!

You need to call
do_settings_sections( 'adt-feed' );
in config-page.php.
A good place to put this is just before the call to submit_button();
