We've tried to follow the instructions here to create some new Smileys & Emoticons
https://stackideas.com/docs/easysocial/administrators/templating/overriding-smileys-emoticons

I added a line in the file /administrator/components/com_easysocial/includes/bbcode/adapters/decoda/library/config/emoticons.json
"shaping": ["(shaping)" ]
And also added the icons
/media/com_easysocial/images/emoticons/shaping.png
and /media/com_easysocial/images/icons/emoji/shaping.png
Typing (shaping) will now make this emoji show. So far so good.

The question is, how do we make this icon show up here?

This appears to be one image /media/com_easysocial/images/icons/emoji/icons-emoji.png
and when we add an emoji in the folder, the first one (angry.png) shows up again at the bottom.
What is the right way to edit this?
Can't find this in the documentation.
