How do I have a team based overhead rank GUI?

Basically, there is an overhead rank gui, it works fine and all on the player added event however I am unsure how I change it after with a different group.

local Player = game.Players.LocalPlayer

Player.CharacterAdded:Connect(function(Character)
    if Player.Team == "Police" then
        local pdId = grouprankhere
        local pdname = script.NameGUI:Clone()
        pdname.Parent = Character.Head
        local pdrank = script.RankGUI:Clone()
        pdrank.Parent = Character.Head

        local namelabel = pdname.TextLabel
        local ranklabel = pdrank.TextLabel

        local PlayerRank = Player:GetRoleInGroup(pdId)
        namelabel.Text = Player.Name
        ranklabel.Text = PlayerRank
    end
end)
