The process of picking up potions is facilitated by the ItemPickupComponent, which is associated with entities representing potions. When a collision occurs between a companion entity and a potion entity, the ItemPickupComponent triggers the pickup action. This action effectively removes the potion from the game world and allows players or characters to benefit from its effects.
