When you buy a game on Microsoft, you get the game on that platform, like for Epic platform.

To have the game on Steam, you have to buy the game on Steam or on a platform that sells Steam keys.  

Only purchases from Steam or Paradox show in your Paradox account. No other platform provides any facility for syncing game ownership.

You bought a non-Steam edition of the game, so there is no entitlement to get a free copy on Steam as well. If you wanted it on Steam, get a refund from Microsoft and buy it from Steam instead.
