Why is Steam trying to load up games with optional parameters?
I am trying to join my friend's Garry's Mod server and Steam is telling me that Garry's Mod is trying to launch with optional parameters. I don't know why, and he is telling me that he does not know.
The code it is trying to run is:
+connect p2p:(a long string of numbers is here).
What does this mean exactly? Should I be concerned? As of now, I have not connected yet.
Update: I tried to join a friend's Borderlands 2 game and it gave me a similar thing.
It tried to run:
+connect_lobby (a long string of numbers)
Is Steam just displaying something it normally doesn't?
Update: It has stopped loading them up with optional parameters, or at least showing me that it has been.

Looking at the SteamAPI documentation, this does appear to be normal:
If the user outside a game chooses to join, your game will be launched with the parameter +connect_lobby <64-bit lobby id>, or with the callback GameLobbyJoinRequested_t if they're already in-game.
I can't find anything in the documentation for +connect p2p, but I'm sure its something along the same lines as the other optional parameter you've seen.

If a game won't launch, this is often caused by corruption in your extracted game files. Please see our Verify Integrity of Game Files article for instructions on verifying the integrity of your game files. Games may not launch if you're running software which interferes with Steam.What does do Steam launch options?
Launch the game that you want to launch in windowed mode. Go to display/video settings. Check if the game has a Display mode option. Click the drop-down menu and select windowed mode instead of fullscreen.Fix Steam Game Not Launching 2022 (General Fix Guide - All games)
