Can't login to directus using route that is written in docs

I'm using Keycloak as provider to login in directus. I can enter Directus web interface using keycloak. But there is route in Directus docs (https://docs.directus.io/reference/authentication.html#login) for login using provider using API.

I get error: { "message": "Route /auth/login/keycloak doesn't exist.", "extensions": { "code": "ROUTE_NOT_FOUND" } }

What is the right route to login in Directus using providers (keycloak etc.)
