Hi there! First of all, thanks for all the work you put into Hydra and the rest of the portfolio! 👏 I've been using Hydra on multiple projects and it has really been a pleasure I am trying to come up with a solution for a customer that wants something akin to the RFC-8693 Token Exchange delegation mechanism. Hopefully Hydra will support it at some point since there is an git issue on it, but for now I need to find a workaround. The idea is to use the oauth webhook to rewrite the token and ad the act claim after some checks. The problem is that I thought I would be able to access the original request in the webhook so that I can extract the data I need. Spesifically we are using the client_credential flow with jwks for authentication and I thought that the jwks would be available in the callback json under request.payload.assertion. Is there some configuration that I've forgotten, or was I a bit to optimistic in my assumptions?
