Hi have a question regarding the release update that is related to oauth "Enforce OAuth Scope for Lightning Apps". This release update says that this update enforce the scope of an Oauth token used to authenticate a Lightning app.This change prevent a Lightning app from using Oauth token with unintended permission. I am confused with this release update about the unintended permission. What does it mean???
