How to become an account recovery contact

To become an account recovery contact, a friend or family member first has to invite you. When they send the invitation, you see a notification in the Messages app on your device. If you're part of their Family Sharing group, you're added as their recovery contact automatically. If not, you'll be asked to accept or decline this request.

Did you ever get an answer? My son sent the invitation and when I click the link it just sends me straight to the apple home page 🤦🏻‍♀️🤷🏻‍♀️ As of now I can’t accept the request.
