Localization in Lang API

my first mod has been reviewed and i was told that

Code:

It is missing the player ID string with the Lang API usage; this is what makes the localization per player possible.lang.GetMessage(key, this, "playeridgoeshere")

i am trying to add that to my code but i am a little lost now, this is my code

Code:

private string Lang(string key, params object[] args) => string.Format(lang.GetMessage(key, this), args);        private new void LoadDefaultMessages()
        {
            //English
            lang.RegisterMessages(new Dictionary<string, string>
            {
                ["ConfigChanged"] = "{0} set to {1}"
            }, this);
        }

and this is how i call the lang to send a message to the player

Code:

SendReply(player, Lang("ConfigChanged"), variableName, variableValue);

i feel like it is something really simple but i dont understand it :c

 

Code:

SendReply(player, Lang("ConfigChanged", SteamIdHere, variableName, variableValue));

 

thanks for answering, if i use that code isnt the steamid going to be used as the first argument? like if it was {0}?

 

so something like this?

Code:

lang.GetMessage("ConfigChanged", this, player.userID.ToString()), args

 

Thank you!
