Living Weapons DLC not available in Microsoft Store

Playing Phoenix Point on Xbox Game Pass and also bought the season pass too. I just noticed that the Living Weapons DLC is not included with the season pass. This weapon pack seems to be not available to purchase individually from Microsoft Store. Is there any way to Buy this DLC?

It should be part of the package. For a while now Phoenix Point is only available as Year One Edition which includes first three DLCs - including Living Weapons.
