[keycloak-user] Get UserStorageProvider Implementation from session

Hello. Is it available to retrieve my custom UserStorageProvider(USP) Implementation from KeycloakSession instance. I defined CustomInterface and add its implementation to my USP, and then in custom Admin Rest endpoint i try to get its instance from session object. session.getProvider(CustomUserStorageProvider.class) == null //true session.getProvider(CustomUserStorageProvider.class, "cusp-id") == null // true session.getProvider(UserStorageProvider.class) == null //true session.getProvider(UserStorageProvider.class, "cusp-id") == null // true but retrieving other provider works fine: session.getProvider(EmailProvider.class) == null // false I tried to deploy my USP via maven-wildfly-plugin and via putting its jar to keycloak_home/../modules anyway i failed to get it from session.
