Lagoon in Steam

[tails]

Hi,
I recently bought Lagoon on the Maniaplanet website for a friend but he was unable to activate the key in Steam. He started Canyon (already bought from Steam) and added a new Lagoon TV by using the key. He can play like this but Lagoon isn't visible in Steam and he would like to have it in Steam for the workshop items. Does someone have any solution ?
I also bought him a Valley key, he activated it directly in Steam and everything was fine

Hi,
You can't redeem Lagoon keys on Steam. For Lagoon, Uplay / Steam and Maniaplanet keys are used on their own plateform and you can't use them outside their plateform.

Ok. Thank you for your response
