Is there a setting to add allowed origins or how would I get this to work?

&gt; Access to XMLHttpRequest at '<https://auth.example.com/sessions/whoami>' from origin '<https://example.com>' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I think I see the problem... need to build an HttpRequest using withCredentials. <https://www.ory.sh/docs/security-model> is good.

I thought I had it but same problem: I've turned off Cloudflare caching and am making the request with dio exactly like the flutter tutorial, but CORS keeps blocking. According to <https://www.ory.sh/docs/security-model#same-top-level-domain> this should work.

I don't think there's anything sensitive in here so...

Embarrassed to say I never added my tld. Problem solved.
