How do i make a local script affect the textlabel on the server?

So, i know that local scripts only affect the client. But i don't know what should i do so the change affects the server as well. Some people told me to use remote events, I do know how remote events work but i honestly have no idea how to change the gui via a remote event. Here's the local script:

local PetName = script.Parent.Name
local PAW = require(game.ReplicatedStorage.Modules.PAW)
local CoinWorth = PAW[PetName][1]
local GemWorth = PAW[PetName][2]
local CurrencyMulti = PAW[PetName][3]
local HatchSpeed = PAW[PetName][4]
local PetImageID = PAW[PetName][5]
local PetLabel = script.Parent.Parent.Parent.Parent.Parent.InventoryLabel.PetExample
local PetIcon = PetLabel.PetIcon
local PetLabelName = PetLabel.PetName
local Multiplier = PetLabel.CoinMulti
local HatchSpeed2 = PetLabel.HatchMulti
local PetAmount = script.Parent.PetAmount
local PetAmountLabel = PetLabel.PetAmount
local function PickPet()
	if game.Players.LocalPlayer.PetsOwned[PetName].Value == true then
	PetLabelName.Text = PetName
	Multiplier.Text = (CurrencyMulti.."x")
	HatchSpeed2.Text = (HatchSpeed.."x")
	PetIcon.Image = PetImageID
	PetAmountLabel.Text = PetAmount.Text
	else
	print("You do not have this pet!")
	end
end

script.Parent.MouseButton1Click:Connect(PickPet)

Could appreciate any help!

script

local rf = Instance.new("RemoteFunction",game.Workspace)
rf.Name = "rf"

again script

game.Workspace:WaitForChild("rf").OnServerInvoke = function(plr, txt)
	for i,v in pairs(game.Players:GetPlayers()) do
		v.PlayerGui."your gui here(without quotes)"."Your label".Text = txt
	end
end

LocalScript

game.Workspace:WaitForChild("rf"):InvokeServer("your text here(with quotes)")
