Assuming you don’t have another image editor, then you can open it in Preview on your Mac, and use the Export option to resave it in a different format- to ensure you get rid of the alpha channel, it might be best to export to JPG (best quality), then open that and export it as a PNG again.
Having said that, I suspect you’re probably OK submitting an icon with a transparency channel as long as there’s no actual transparency.
