Sharpening scissors with microserrations

I own Sabatier Proffessional scissors (like those). One of the blades has microserrations along the edge (see the picture below). How should I sharpen them? I presume that I’d destroy the serrations if I just tried sharpening it the same way as I do with non serrated edge?

As far as the tools go, I own Work Sharp Knife and Tool Sharpener (which I like very much) and Spyderco Sharpmaker (which I was not able to use to its full potential, hence replaced that with WSKT).
