我已经创建了一个自定义帖子类型“book”。所有书籍帖子类型都是公共的，因此我想删除一些功能，如“delete\\u private\\u books”、“read\\u private\\u books”等。我如何实现这一点，因为当我激活成员插件时，它会显示所有默认功能，包括上述与我的自定义帖子类型无关的功能。

我已经注册了我的post type book并为其添加了功能。

  \'name\'               => _x( \'Books\', \'post type general name\' ),
  \'singular_name\'      => _x( \'Book\', \'post type singular name\' ),
  \'menu_name\'          => _x( \'Book\', \'admin menu\' ),
  \'name_admin_bar\'     => _x( \'Book\', \'add new on admin bar\' ),
  \'add_new\'            => _x( \'Add New\', \'Book\' ),
  \'add_new_item\'       => __( \'Add New Book\' ),
  \'new_item\'           => __( \'New Books\' ),
  \'edit_item\'          => __( \'Edit Books\' ),
  \'view_item\'          => __( \'View Books\' ),
