Yes I noticed. I was able to integrate it into my SDK and successfully requested my Cashu-address balance using nsec.app 👏 great work btw… However request-id is the random string from my request, not an event id right? I want to build a set of asynchronous functions that send a request and then resolve once I get the response, but from what I can tell there is no way to subscribe to ONLY the response, because the response does not include the requests e-tag, right?
