For context to others: The plugin should provide options to share WordPress Posts to Nostr.
nostr:npub1g3827ewz6d23rlgdhkaslc78gyule52ymcqdyt2hsxdwtlw8dt5q7dfpvg As far as I can understand NIP-07 requires a JavaScript implementation. This could work, if the "share to Nostr" functionality would be a dedicated interaction in the WordPress admin area which triggers an action to the window.nostr object.
This would have some tradeoffs for automatically share new posts to Nostr if they get published by schedule.
Or let's say, to share a post to Nostr, the pleb with the extension for signing needs to be around when a post gets published.
What do you think is more convenient, to have an auto-share mechanism or to not have to store your nsec in your WordPress Setup?
