Free Specialist Tokens in Rebirth Island - The Forgotten Keycard Easter Egg

You NEED to interact with the shower to get it to spawn - Thanks to Micleo777 for showing me where this card is. This Rebirth Island Warzone Easter Egg lets you get specialist tokens for your whole team and a loadout marker near the start of a match. This is the second of three keycards to find on the island, does anyone know where to find Perseus?
