additionalLaunchArgs

A list of CLI arguments that are sent to the streaming server when a stream session launches. You can use this to configure the application or stream session details. You can also provide custom arguments that Amazon GameLift Streams passes to your game client.

AdditionalEnvironmentVariables and AdditionalLaunchArgs have similar purposes. AdditionalEnvironmentVariables passes data using environment variables; while AdditionalLaunchArgs passes data using command-line arguments.
