Is there a way of knowing the local player in a normal script?

Hello people, i think i have been bugging the forums with my begginer issues, but there is the deal:

I have a Filtering Enabled game, and after watching the wiki and seeing a alvinbloxx video, i learned how to use clickdetectors in filtering enabled, and how remoteEvents work.

The thing is, inside a RemoteEvent i used a script that is this:

game.Workspace.GivePizzaEvent.OnServerEvent:Connect(function()
game.ReplicatedStorage["Pizza"]:Clone().Parent = game.Players.LocalPlayer.Backpack
end)

As us know, "LocalPlayer" cannot be used inside a normal script, resulting in a "nil"

However, i need us to tell me how can i detect a localplayer with a normal script, so i can give that item to the player.

Not only that, but i have a gamepass to give fireworks, that executes the same command.
