Display only child pages in a relationship field within a block

Is it possible to modify the relationship field to display only child pages of the current page within a block?

Using this filter ‘acf/fields/relationship/query’ I don’t know how to pass the current page id, because within the block $post_id is null.

add_filter(‘acf/fields/relationship/query/name=child_pages’, function( $args, $field, $post_id) {
// only show children of the current post being edited
$args[‘post_parent’] = 2190;

return $args;
}, 10, 3);
