Auth0 cors error coming auth0/token api even after adding my domain in allowed cors origin

I am getting cors error while try to call auth/token api endpoint

Access to XMLHttpRequest at '' from origin '' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I added the domain in allowed cors origin is there anyway to work around this.

I have same issue. REactjs app gets this. Did you figure it out?

I have the same case. Has anyone solved it?
