(CN server) --run-game option not working

[Linus-XZX]

SteamOS 3.5.13, launcher version 1.6.0 (Flatpak from Discover), CN server

It seems that the --run-game and --just-run-game options do not function in this launcher, unlike the other two launchers for the same company. Adding them results in the program hanging up and not starting the game. Verbose output for the former is attached below.

Unknown option --run-game

The options are referenced in src/main.rs here, but I do not know the language well enough to track the operations from here.

for i in 0..args.len() {
        if args[i] == "--debug" {
            force_debug = true;
        } else if args[i] == "--run-game" {
            run_game = true;
        } else if args[i] == "--just-run-game" {
            just_run_game = true;
        } else if args[i] == "--no-verbose-tracing" {
            no_verbose_tracing = true;
        } else if args[i] == "--session" {
            // Switch active session prior running the app
            if let Some(session) = args.get(i + 1) {
                Sessions::set_current(session.to_owned())?;
            }
        }
    }

It does not affect anything if I start the game normally through the launcher, but I would greatly appreciate it if this issue can be addressed. Thanks in advance.
