###### g_app_launch_context_get_environment

Gets the complete environment variable list to be passed to the child process when `context` is used to launch an application. This is a `NULL`-terminated array of strings, where each string has the form `KEY=VALUE`.

###### g_app_launch_context_get_startup_notify_id

Initiates startup notification for the application and returns the `XDG_ACTIVATION_TOKEN` or `DESKTOP_STARTUP_ID` for the launched operation, if supported.

###### g_app_launch_context_launch_failed

Called when an application has failed to launch, so that it can cancel the application startup notification started in `g_app_launch_context_get_startup_notify_id()`.
