With new work like this I'd be inclined to scrape the entire edge, give the corner a light sanding, and apply new finish to the entire length. The scraper will make short work of the poly and the whole process will go faster than feathering the existing finish, spot finishing, leveling, and rubbing out to make it look uniform...

There is excellent merit in John's recommendation. If you're not in so much of a rush, maybe do the spot repair, for practice. If you ever have an old piece, that needs matching/blending colors, gloss, etc., for a spot repair, you'll have some experience. Take this easy opportunity to do some practicing, if not in a rush. If, after your "practice" session, you are not completely satisfied with the results, you can do as John says, scrape, prep and refinish the whole, since it shouldn't take long, at all, to scrape, prep, refinish the whole edge/edges.

For an older piece, you might not want to do your first time attempt/practicing of spot repair on the/an original.
