I imagine players would be notified by the end of the auction if they were or were not selected.
Given that there are close to 100 players in this league, it would be very tedious to notify every player. It is up to the managers to handle the players they sign and build their roster(set up chat games etc.)
From a player's perspective, they can check the spreadsheet(section > Clubs) at the end of the auction to see if they were selected.
