Sorry I got it wrong. I read your codebase, you want to export a .ics file to the local file system in a background process. Actually, it’s impossible that plugin API to write local files anywhere for security. We planned to provide an storage layer API that could support files manipulation in specific file root (like ~/.logseq/storage/xxx-plugin-id/could-write-any-file-here.ics).
So what do you think?
