It’s almost certain that bread yeast (what is being used here I assume) is going to have a pretty limited set of enzymes- probably amylases to convert the starch in flour into sugar for the yeast’s own use, and possibly some proteases. The orange peels aren’t likely to be significant sources of enzymes I wouldn’t expect.
But the kicker is that enzymes tend to work best in certain temperature bands, and they aren’t necessarily instantaneous. So even if somehow you managed to get enough amylase out of your yeast fermentation to do something, there’s a good chance your countertop is going to be the wrong temperature, and you’re unlikely to leave it on there long enough.
