No Dlc's Available To Buy When Using The Microsoft Store/xbox Gamepass Version

Dear people at DTG,

I cannot find any DLC's for the game via the Microsoft store. I was wondering if anyone would know how to fix this? I have an Xbox where I bought the base game and some DLC's so I am playing my DLC's on that currently, but I would like to get them on my PC.

Is this possible?

With best regards,

Chiel

Add-ons only work on console. Microsoft Store only has the base game compatible with PC and Xbox platforms.
