Add passive ability withou showing it's icon

[MN Lahmar]

Hello guys,
Can i add a passive ability to a hero without showing its icon or tooltip in the abilities UI? (I did something similar years ago with spell book but i can't remember how )

Thank you.

In older versions: add the ability to a spellbook, add the spellbook to the unit and disable the spellBook for the units owner.
Warcraft 1.28+ (not sure about 1.27) set abilitys Button-Position to: x = 0, y = -11

Thanks guys. I run into a probelm. The spell book loses its sub-spells when the unit uses Metamorphosis.
How can i fix that?

You need to make the spellBook and it's content permanent, with this native UnitMakeAbilityPermanent takes unit whichUnit, boolean permanent, integer abilityId
