nostr client devs who have not implemented nip-46 login yet, this is all it takes to sign an event using nip-46. Maybe we should add an example like this to the nostr-tools docs. Not sure if people realize it's this easy. I used nsec.app as my remote signer for testing. nsec.app logs a lot of info in the dev console when you send nip-46 requests which is helpful for debugging.
