LayerStyles / Appearance API

Hi, I'm trying to generate our color palette in sketch with react-sketchapp, from the documentation react-sketchapp supports Symbols and TextStyles, what about layer styles?

Example:
I can run the color palette example, but each element of the palette only has direct styles applied to it, I'd like to use layer styles like this 👇

Any pointers would be appreciated, otherwise I guess I'll have to use sketch's low level api?

Start by reviewing the documentation for Symbols and TextStyles and the color palette example referenced in the issue. Determine whether layer styles or the Sketch Appearance API are supported, then define completion as either documenting the supported layer-style usage or adding the requested API support with a working palette example.
