Legacy Contact is a new feature introduced by Apple in iOS 15.2, iPadOS 15.2, and macOS 12.1 that allows users to designate up to five people who can access their Apple account and data after they pass away. Legacy Contacts need to have the unique access key that the user created when they added them as a Legacy Contact, and a copy of the user’s death certificate, to request access to the user’s account. Legacy Contacts can access data stored in iCloud, such as photos and documents, but not services that require subscriptions, such as Apple Music or Apple TV+. The other options are not valid services offered by Apple.  References :  How to request access to a deceased family member’s Apple account ,  How to set up Apple account access so people can get in after you die
