Help With Redoing The Job Voting UI And Keys UI, Also Hiding The Spawn Menu

[Bojack]

Hi I want to redo these two UI's but i'm not sure where I can edit them.

Also I want to make it so only certain groups can open the spawn menu. This is what I have so far, but I want to add more groups like: admin, and senioradmin

function GM:SpawnMenuOpen()
    if ( LocalPlayer():GetUserGroup() != "superadmin") then
        return false
    else
        return true
    end
end
