Abomination's new ability help

[Rykon-V73]

I created the ability called 'Remains', which allows the Abomination to store 4 spiders within its body and can evacuate to help you, after death. Yes, the ability works, but when the Abomination appears, the icon doesn't show up. I really don't mind, but I really want to know how to do that:
Here are the options:
Abomination options:
...
Abilities - Normal Remains, Cannibalize, Disease Cloud(Abomination), Unit Inventory(Undead)
...
Techtree - Upgrades Used Remain, Unholy Armor, Unholy Strength, Disease Cloud, Backpack(Undead), Glyph of Ultravision(Upgrade), Undead Maximization(raises hp of every undead)
...

Next, I made the Remains ability, based off the Summon Spiderlings and then did the following:
In the Abilities section:
...
Art - Icon war3Imported\PASSpiders.blp
...
Data - Number of Units 4
Data - Unit Type Spider
...
Techtree Requirements - Remains
...

I actually examined the way this is done in Curse of the Forsaken and there, it has the same icon for Outbreak(or Remains in my case). I'm not sure what it's based off, but except for the 2 data options mentioned above, it was the same. I added Shown, like in the example below:
...
Text - Editor Suffix (Shown)
...

Finally, I made the Remains upgrade. I included it in the Graveyard building. Most of the abilities are like this, except for a few things. I did edit the techtree requirements:
...
Techtree Requirements - Black Citadel, Tomb of Relics, Graveyard
...

That's what I did. The ability works, but how can I make the icon show up for the Abomination?

Some abilities are alawys hidden. Use a additional dummy ability (moon glaives), so that you can display an icon.

I checked the Curse of the Forsaken campaign and that one doesn't even use a dummy. Maybe the Outbreak(shown) is the one, but I'm not sure. Also, I tried to open the Trigger Editor there, but no luck.
Edit: I see what you mean. I did try it and it worked! Thanks!
