Before you can use the plugin to work on Figma frames, was this intended in the latest release of the plugin? Here's what I [found](https://github.com/aaroniker/figma-remove-bg/blob/22f34f9c6af3765f4ca0fec985f9f6befc67beca/src/code.ts#L39-L55), apparently it is now only processing specific nodes e.g. Polygons or Squares.
