Hello @Raccine, any news on this topic? I have almost same problem as @Marinos Stylianou. I need to access clientId in action ctx to could add claims depended on client. Ideally there would be something like Metadata for client which would be injected into claims (as by user with scope :metadata). The fact that Zitadel do not allow to set the clientid for the application doesn't make it easier. All applications getting clientid by creating so the backend code have to be aware that there are different clientids on each stage (test,prod) for the same type of application.
