That looks like either a gloss, or clear topcoat of polly, probably sprayed onto veneer or MDF. But super small, so easy to hide. You might try sanding that more flat, primer, then a wood bondo/filler. You don't have to go nuts tho, just give the primer something to grab and make the edge easier to bond and bury, sand too much and you can blow thru the veneer.

I would lay it flat on a bench or horses, for work, use a rattle can primer, shook xtr well, test the spray on scrap, and if it spits, use a foam roller to lay it flat. Filler and sand the filler flush n smooth, primer again, then paint. Less is always more. Both filler, and paint.
