Hello!
We are trying to set up an experiment for new users coming to our site. For this experiment experience to show, you have to create a new account on our site.
We are trying to push this experiment out into a live environment, but restrict it so that only our dev team can see the experience. But that said, the ability to add testers only via device or User ID seems to imply that this only works with registered / pre-existing users.
Does the Testers functionality only work for users that already have a registered account with us? Or can we set this up in a way where Amplitude Experiments knows its my team even without having created an account?
