Model return id record

What are the ways to return the id of the created record in the table?

PHP Code:

  public function insertAny($title, $slug) {
    $this->table('node')->protect(false)->place([
      'title'    => $title,
      'slug'     => $slug
    ])
    return ID of record? ;
  } 


Because I have only one idea, this is to create an additional unique field on which, after executing the record, perform a search and return the ID. But I think there should be some solution out of the CI box.

P.S
Thank for your attention!
