openid-connect-spring-client | OpenID Connect client using Spring Security | Authentication library

i'm plugging a Spring security application to an IDP/OP (IDentity Provider, or Openid connect Identity Provider according to the OpenID connect terminology)

I'm using the authorization code flow. I used this implementation to start my code : https://github.com/gazbert/openid-connect-spring-client

It's working with several IDP, until i found one that requires the nonce parameter. However i could not managed to configure my application to generate a nonce, and add it in the url (I know that's the nonce because when i add it manually : it works)

It's when the application redirect the user to the IDP (authorization endpoint) that i wish to have a nonce. And it would be perfect if the nonce could be verified on the return.

I searched the web for 2 hours, i found this may be the thing to use org.springframework.security.oauth.provider.nonce but didn't found any example, or clue on how to add it in my code

Here is the interesting part of the code where i think i have to tell Spring to use the nonce :
