Login with Facebook and merge with an existing account

[claudious]

Hello,

I want to add login with facebook to my site using the SFCC out of the box feature for customers authentication using oauth2 providers.
Customer Authorization with OAuth2
However, when I implement it, I can not find a way to merge accounts for customers previously registered on my site and then authenticates with Facebook. In this case, the customers are created as new customers and can not use his saved data (addresses, credit cards, etc.)

If any of you had this problem and solved it in some way, I would appreciate any advice.

Thanks in advance.
regards
Claudio
