Click the green + next to the refresh button or after searching for the game click "Add Game"
Next, you'll see the Add a Game screen. Click browse and navigate to the game's installed location. Double click on the "Application" that is used to launch the game. In this example, I'll use Icarus.
After you apply the application, you'll then need to locate the launcher the game is played on. For Icarus, this would be Steam.
Once the pathing is found, click Add Game at the bottom.
