How to remove Customize from admin menu bar after WP 4.3

WordPress 4.3 brought more updates to the customizer. It also added a new option at the top admin menu bar that says ‘Cusomize’ and has a paintbrush. How can I disable this menu from showing up? We don’t use the customizer, and I would not like our users clicking on it either.

We currently do $wp_admin_bar->remove_menu('comments'); but I do not know the term for the customizer. I tried both customize and customizer (guessing) but neither seemed to work.

customize should work. I was able to remove the Customize link with the following code:

add_action( 'wp_before_admin_bar_render', 'wpse200296_before_admin_bar_render' ); 

function wpse200296_before_admin_bar_render()
{
    global $wp_admin_bar;

    $wp_admin_bar->remove_menu('customize');
}
