Change webhook to server.lua file since your webhook is in a shared file that means any client on the server could easily find it and abuse it.
Put the files directly on github and not in a .rar file - Since this is against the rules of posting on the forums it must directly lead to the files OR you could just put the .rar file directly in the post and that would be fine also
Also might want to remove your webhook from there unless its a channel/discord you dont use
