ReaderInterceptor & WriterInterceptor for keycloak

Getting advice
1

I am able to use ReaderInterceptor, WriterInterceptor to catch API call related info after registering it to “RealmResourceProviderFactory” using below :

ResteasyProviderFactory.getInstance().getServerReaderInterceptorRegistry().registerSingleton(RequestResponseFilter.INSTANCE);
        ResteasyProviderFactory.getInstance().getServerWriterInterceptorRegistry().registerSingleton(RequestResponseFilter.INSTANCE);

How can I register it at Keycloak application level to intercept all calls, including non-API calls ?
