We don't have any direct way to search within Paragraph for specific writers or publications / blogs. We hear this all the time though & something very much top of mind.
We don't have a button to share a publication, but if you copy & paste the link, you'll almost always see a nice-looking embed (like the one below for https://paragraph.com/@blog).
IMO, connecting your Substack to your Paragraph is much easier than copying & pasting every new post to Paragraph. Perhaps there's a formatting issue or bug the other person was encountering?
