[keycloak-user] help with getting users from angular app

Hi list, I have an angular app that is configured to login with keycloak, I have configured web-origin and the login is working well, now I want to get all the users from my realm and i am calling to http://<host>:<port>/auth/admin/realmns/<realm_name>/users? but this is answering with 404 and error in console for cors. zone.js:2969 OPTIONS http://<host>:<port>/auth/ admin/realmns/<realm_name>/users ? 404 (Not Found) scheduleTask @ zone.js:2969 ZoneDelegate.scheduleTask @ zone.js:407 ...... localhost/:1 Failed to load http://<host>:<port>/auth/ admin/realmns/<realm_name>/users?: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access. any help will be appreciate.
