Passing a function to `add_options` still gets called on every admin page

[speedwheel]

This is my code:

<?php
use Carbon_Fields\Block;
use Carbon_Fields\Field;

add_action( 'carbon_fields_register_fields', 'register_package_block' );
function register_package_block() {
    Block::make( __( 'Package' ) )
    ->add_fields( array(
        Field::make( 'select', 'package', __( 'Package' ) )
        ->add_options('get_package_options'),
    ) )

    //->set_icon( 'format-image' )
    ->set_preview_mode( false )
    ->set_category( 'page-content', __( 'Page Content' ), 'smiley' )
    ->set_description( __( 'Block containing a list of packages.' ) )
    ->set_render_callback( function ( $block ) {
?>
         // html
<?php
    } );
}

The function get_package_options makes an HTTP request using CURL which takes couple of seconds to finish. The problem is that this function gets called on every admin page that I navigate to and makes each page to load in 5+ seconds, instead of 500 miliseconds (when I remove this select field).

I've read the aricle here: https://docs.carbonfields.net/#/fields/select?id=performance-implications but it seems that it's not behaving like it should.

I want this function to be called only on the edit post where it's being used.

Any tips?

Came here to open this issue too, can confirm!

Field::make( 'select', 'email_template_for_password_reset_link', __( 'Template : lien de modification de mot de passe', 'freebulle' ) )->add_options( [ '\Freebulle\Emails', 'get_transactional_templates' ] ),

The get_transactional_templates() method does an API request to get data (a list of templates from SendInBlue) and I noticed that the call is made on any admin page.

It should only be triggered on the page where the CF container is displayed.

Sorry, the call is not made on all admin pages. It's triggered randomly and I can't seem to find a common event for all these calls.
