Group Rank Tool script isn't adding tool to the player inventory on spawn?

The tool is in ServerStorage, I believe the fault is at the end where it finds the ranks needed.

local groupId = 6998516
local tool = game.ServerStorage['Cleaning Equipment']
function onPlayerSpawned(player)
	if player:IsIngroup(groupId) then 
		tool:Clone().Parent = player.Backpack
	end
end

game.Players.PlayerAdded:connect(function(player)
  player.CharacterAdded:connect(function()
    onPlayerSpawned(player)
  end)
end)

function onPlayerSpawned(player)
  if player:GetRankInGroup(groupId) = {252,253,254,255} then
    tool:Clone().Parent = player.Backpack
  end
end
