Whatever we pass to uri it is still 401 always. EG urls are 401

https://remote.api.com/.well-known/mercure/subscriptions
https://remote.api.com/.well-known/mercure/subscriptions/%7Btest%7D
https://remote.api.com/.well-known/mercure/subscriptions/%7Btest%7D%7Bchat%7D

 add(key, url, onMessageCallback, onOpenCallback = undefined) {
        this.delete(key);

        const event = new EventSource(url);

        event.onmessage = onMessageCallback;

        if (typeof onOpenCallback !== "undefined") {
            event.onopen = onOpenCallback;
        }

        this.eventMap.set(key, event);
    }

Stil topics urls works fine, except subcriptions even it is exposed in caddy mercure config and anon allowed.

Why 401?

Well from the docs we see that JWT requires subscrive['*'] encoded for susbcriber, but the thing is, polyfill suggested by mercure and symfony has empty EventStream tab which makes it impossible to debug. https://mercure.rocks/docs/hub/troubleshooting EventStream tab must work. It is mercure docs and polyfill issue.
