I want to award a badge to people that have a specific role in my group

[Mochidrift (mentos prime)]

@BirdieI90

local Players = game:GetService("Players")
local BadgeService = game:GetService("BadgeService")

local GroupId
local BadgeId
local RankId

Players.PlayerAdded:Connect(function(Player)
	if Player:GetRankInGroup(GroupId) == RankId then
		BadgeService:AwardBadge(Player.UserId, BadgeId)
	end
end)

Where should I put it? e.g. ServerScriptService and how do I format the script as (Local script or just a normal script?)
