Character Creator Help

So ive made a character creator and it works fine but i wanna make it that once the intro ends the gui is already opened so that they can create their own character once they make it they can hit confirm , although the gui button which opens it will stay so that they can edit t when needed

How would i make the gui appear on start ( i dont want it to appear everytime when they join , just when they join for the first time)

Heres the model i made Feel free to experiment with it
(must turn on api services for it to work)

maybe a script/video could help, but it sounds like you need to do something when a player joins, and only once

game.Players.PlayerAdded:Connect(function()
  --blah
end)
