Kindly requesting minimal example for styling custom prop controls (using a theme context provider)

Hi. I am trying to apply styling to custom prop controls (using React Spectrum UI components) and I have tried to follow the documentation and provide the appropriate contexts to the custom prop controls, but it isn’t quite working.

I have outlined what I have done in a previous thread on the Plasmic community forum:

At this point, I am hoping that someone could point out if I have overlooked anything or if there are any mistakes in my code or - at minimum - provide a minimal reproduceable example of how to pass theme contexts to custom prop controls rendered in the Plasmic host. Thanks!
