SBW on Nostr: BIP322 outlines how to sign and verify a message, but what about formatting a result ...

BIP322 outlines how to sign and verify a message, but what about formatting a result such that it can be presented as QR for example, is there any standard for that?

For example, to verify I need to get an address, a signature and a message, so 3 strings.

Is there is a format to pack those into something QR-readable/copy-pastable?
