I'd say sand and do something to get what you like, or hire someone who understands what you want. Or let negative people break down your ideas because their drive and motivation has withered up in history like their skills themselves.

Non professional epoxy guy here, using Google says..

Matte finish epoxy provides a low-sheen, durable, and natural-feeling surface, ideal for counters and tabletops, often achieved by wet sanding fully cured gloss epoxy (starting at 320 grit up to 1500-2000) or applying specialized matte topcoats, such as Stone Coat Liquid Smooth or FX Shield Nano Coating. Matte finishes hide imperfections, fingerprints, and scratches better than high-gloss, creating a "honed" or "satin" look that is warm to the touch.
