Gutenberg Block buisnesswoman dash-icon not showing

Using WP 5.4.2 adding Gutenberg blocks via ACF, most dash icons seem to show without issues when pulled in as an ‘icon’ (e.g. facebook, sort, businessman) but for some reason ‘businesswoman’ doesn’t. e.g:

acf_register_block( 
      array(
        'name' => 'business-testimonials-block',
        'title' => __('Business Testimonials Block'),
        'description' => __('Testimonials about Business.'),
        'render_callback' => 'business_acf_block_render_callback',
        'category' => 'formatting',
        'icon' => 'businesswoman',
      )
    );
