Spring Boot : How to get all user attributes from Raw Json and shown in User dashboard


I am following this tutorial : https://auth0.com/docs/quickstart/webapp/java-spring-boot/01-login and I have added Github social connection to my current app. In the user dashboard I can see lot of attributes as raw json data for my user which is part of Identity Provider Attributes. However in my Spring Boot application I am only able to access few attributes such as name, email etc. which are part of OIDC standard claims if I am not wrong, in the tutorial this is being resolved as DefaultOidcUser object. How do I access all the attributes in my application?
