Is there any documentation showing the names of the Gutenberg block icons within the WordPress docs?

Gutenberg block icons

To give you some context, I'm using ACF blocks for Gutenberg, and need to find a reference for 'icon'.

add_action('acf/init', 'my_acf_init');
function my_acf_init() {

    // check function exists
    if( function_exists('acf_register_block') ) {

        // register a testimonial block
            'name'              => 'testimonial',
            'title'             => __('Testimonial'),
            'description'       => __('A custom testimonial block.'),
            'render_callback'   => 'my_acf_block_render_callback',
            'category'          => 'formatting',
            'icon'              => 'admin-comments',
            'keywords'          => array( 'testimonial', 'quote' ),

Gutenberg is making use of dashicons.
You can find your example icon here, and a cheat sheet of dashicons here.

    Many of Gutenberg's icons are custom SVGs, so don't expect to find all of the icons on the dashicon list. You can also pass in a custom svg to the ACF block registration, though. – tmdesigned Feb 12 '19 at 10:44
  • On this occasion, the dashicons work for what I need. I'll look into custom SVGs for ACF, thanks. – Sam Feb 12 '19 at 11:34
