No, because you don't techncally "own" them yourself

Steam family?

<mention>timeTr<mention>veler</mention></mention> Family Sharing allows other users of different accounts to access Steam Games on a single account, this allows multiple users to prevent buying excessive games on multiple accounts but can't play the same game at the same time

Because it needs to be owned by you.

Probably a limitation of the software connecting AWA to Steam.

Because the game is not tied exclusively to your individual Steam account.
