[keycloak-user] How update the locale value in user profile with REST API ?

Hi, I use the doc to update my profile with REST API PUT /{realm}/users/{id} but if I want to change the locale value ("en", "fr"...), it's impossible. I have this response "Unrecognized field "locale" (class org.keycloak.representations.idm.UserRepresentation), not marked as ignorable" because in my body object I use "locale" key for "en" value for example. I don't see in the doc how send my new locale value in my body object. Thanks for your help 😊
