              Hi Mikhail,
Please try this one 
<script type="text/discourse-plugin" version="0.8">
  api.replaceIcon('notification.granted_badge', 'oo-medal-badges');
</script>
 
You can find these replacements here

              And where can I see what they look like?

const REPLACEMENTS = {

              You can easily identify it by using inspect elements.
For example.: the certificate  icon notification
Find the icon name with inspect elements 
 
 
Find the same icon in the icon-library js 
 
  
  
    
      
      
            "notification.liked": "heart", 
            "notification.liked_2": "heart", 
            "notification.liked_many": "heart", 
            "notification.liked_consolidated": "heart", 
            "notification.private_message": "far-envelope", 
            "notification.invited_to_private_message": "far-envelope", 
            "notification.invited_to_topic": "hand-point-right", 
            "notification.invitee_accepted": "user", 
            "notification.moved_post": "sign-out-alt", 
            "notification.linked": "link", 
            "notification.granted_badge": "certificate", 
            "notification.topic_reminder": "far-clock", 
            "notification.watching_first_post": "discourse-bell-one", 
            "notification.group_message_summary": "users", 
            "notification.post_approved": "check", 
            "notification.membership_request_accepted": "user-plus", 
            "notification.membership_request_consolidated": "users", 
            "notification.reaction": "bell", 
            "notification.votes_released": "plus", 
          }; 
          
       
 
    
   
   
  
    
    
  
  
 
Then you can replace the icon with any other icon you want.

              Thanks for your reply 
I figured it out. I thought there was some sort of list with standard Discourse icons

              May I add this for future reference. I followed the instructions on Replace Discourse's default SVG icons with custom icons in a theme - #19 by dodesz  but but what I did not realise at first was that the same icon can be referred to in different ways. In the app itself, under ‘/styleguide/atoms/icons’ is a list of all the icons and how they are referred to, so in my header.html file I now have 5 references to the envelope icon:
    api.replaceIcon('envelope', 'fgx-air-mail');
    api.replaceIcon('far-envelope', 'fgx-air-mail');
    api.replaceIcon('notification.private_message', 'fgx-air-mail');
    api.replaceIcon('notification.read_private_message', 'fgx-air-mail');
    api.replaceIcon('notification.invited_to_private_message', 'fgx-air-mail');
