Which book can I find the Paladin Oath of Heroism

[Release]

I'm running Fantasy Grounds Unity with the following books:

Player's Handbook
Dungeon master guid
Element Evil player companion
Sword coast adventure guides
Xanathar guide to everything
Mordenkainen tome of foes
Unearthed Arcanad



When I raise a paladin to level 3 I don't have the heroism oath choice. I've searched in the paladin class description, I can't find it. How do I get access to this oath?

Thanks!

It's in Unearthed Arcana Players module.

Oh, my bad. I've only loaded the DM module, not the player one. I though the player was the DM version adapted for players. Thanks!
