How do i Enable ScreenGuis using a Script (local or server)?

Basically it's a bit like my other question but forget that.

So i inserted a ScreenGui into StarterGui which will end up in PlayerGui when testing. Inside that ScreenGui, I inserted a Frame, and inside that frame, a LocalScript and Textlabel, and what i want to do, is make it so if "Script 1" (which is a ServerScript in Workspace) activate the ScreenGui (and maybe the LocalScript also)

Script 1:

function onClick()
    game.Workspace.Eggs.Egg1.Transparency = 1
    game.Workspace.Eggs.Egg1.CanCollide = false
    game.Workspace.Eggs.Egg1.CanTouch = false
    game.Workspace.Eggs.Egg1.egg: Play()
end

script.Parent.MouseClick:Connect(onClick)

LocalScript inside of PlayerGui:

local textLabel = script.Parent:WaitForChild("TextLabel")

wait(3)

local function typewrite(object,text, length)
    for i = 1,#text,1 do
        object.Text = string.sub(text,1,i)
        wait(length)
    end
end

typewrite(textLabel, "Looks like you found an egg...", 0.0005)
wait(2)
typewrite(textLabel, "A reward might follow if you find all the other eggs...", 0.0005)
wait(2)
