Onboarding: user not taught *how* to open the security-slider dialog
"Security" / "Choose your experience" / "Review Settings" Onboarding screen doesn't direct the user how open the security-slider dialog outside of the Onboarding screen.
A user may want to open this dialog again, and potentially knowing how to return to Onboarding, they may take a very inefficient path through the Onboarding functionality instead of the simple means.
