Using OIDC auth and enrich signal

[sushiMix]

Hello, I'm trying to perform a test with open telemetry collector to receive an external log validate the authentication using OIDC and try to add such identification to the log itself (as attribute for example).
Activating the OIDC authentication is done and working well.
It seems a context is created in OIDC auth extension but I can't find a way to use it to enrich my log (using transformer processor)?

Does somebody knows how to copy the context.Auth in the log attributes for example (I can't find such dynamic sample) ?
Is it currently doable or do I need to write my custom processor ?

I did a small sample code but would have preferred to be already provided by transformers
