Adding UI elements above health bar?

Hello all
I'm trying to add custom UI elements to this list shown below. The game automatically stacks these ui elements. Notice the sulfur ore pickup message is automatically shown above the custom "ZONE SHRINK".



I have tried CUIElements and looked at numerous plugins to see if any acheieve this but no luck.
What is this list called? What these elements called? Would anyone mind giving me some guideance on how to acheieve something like this?

Isn't that the game crafting popup? maybe they're using that and just changing item name or something

It is but it also shows like "Wetness" and "Radioactive" etc and I'm struggling to find out what sort of data was sent from the server to get Rust to put items into this list

Ah I think I found how they did it!
