Missing updating, deleting, and adding an interest of a group,

[Tamarpe]

There are no functionalities for all those operations for interests of a group beside get.
Example of an adding one:

  public function addInterest($list_id, $group_id, $name, $parameters = []) {
    $tokens = [
      'list_id' => $list_id,
      'group_id' => $group_id,
    ];

    $parameters += [
      'name' => $name,
    ];

    return $this->request('POST', '/lists/{list_id}/interest-categories/{group_id}', $tokens, $parameters);
  }
