Is ARK free on Game Pass?

Excuse me, I was wondering if I could clarify something regarding ARK and Game Pass. Specifically, is the game ARK available for free through the Game Pass subscription service? I'm considering subscribing to Game Pass and would love to know if this particular game is included in the lineup of free games that come with the subscription. Could you please shed some light on this matter for me? Thank you very much in advance for your assistance.
