How to make Gui visible to every client using fireallclients?

local UpdateTextGui = game.ReplicatedStorage.MakeAuctionVisible

-- Allow the clients to request the data immediately
UpdateTextGui.OnServerEvent:connect(function(player)
    UpdateTextGui:FireAllClients()
end)

server

script.Parent.MouseButton1Click:Connect(function()
	print("Auction clicked")

-- We named our RemoteEvent "UpdateTextGui"
local UpdateTextGui = game.ReplicatedStorage.MakeAuctionVisible
local player = game.Players.LocalPlayer

-- Hook into the event and change the GUI text
UpdateTextGui.OnClientEvent:connect(function()
	print("event executed")
	player.PlayerGui.Auction.Frame.Visible = true
		player.PlayerGui.Auction.Frame.Lots.Text = "Islamabad"
UpdateTextGui:FireServer()
print("Fire Server")
end)
end)

local I want to fire server from the player and the player to fire all the clients, for a gui to be visible for everyone. I dont want to loop through all players to make this happen. I want it done using remote events. Wat is my mistake? Why isnt my script working? (I want this to happen when a text button is clicked)
