Requires the Meta Box plugin on WordPress 6.9+ for the Abilities API (abilities are registered only when the wp_register_ability() function exists). The get, update, and delete abilities additionally require the target key to be a field Meta Box actually recognizes (verified via rwmb_get_field_settings) and the current user to hold the WordPress capability mapped from object_type: read_post/edit_post for posts, assign_term/edit_term for terms, read/edit_user for users, read/manage_options for settings pages, and read/moderate_comments for comments.
