[2022] Where and how to get Icon from item in the game files ?

Hello my fellows ecogamers !

Recently I'm trying to make an Excel and I use the icons from the game as a reference for the items on the document.

Problem, not all the images are yet implemented in the wiki. Per example, for the Fungus Tag : https://wiki.play.eco/en/Fungus_Tag there is no icon on the wiki even is it's present in game.

So my question is , where is the file that contain the icon and how can I get the icon ?

That way I can complete the wiki and also my Excel.

Thanks a lot
