Accessing Trackmania Store Through Steam

[Nerdonis]

Hey guys if this question has been answered, I apologize for reposting!

I am trying to get the Assassin's Creed cars for Canyon, but having bought the game through Steam I can't seem to get access to the supposed in-game store. Does anyone know of a way for me to get these cars/access to the store or is it a lost cause?

Thanks!

Ingame, write "maniaplanet-store" in the top bar at left.
