CSS variable to Figma colour variable

Hi

I’m looking for a plugin to convert CSS colour variables to Figma colour tokens.

For example, I could feed the plugin these two CSS colour variables

  --card-okay-icon: #4ade80;                  
  --card-okay-icon-bg: rgba(74, 222, 128, 0.2);  

and plugin would produce screengrab below.

I can find lots of plugins doing it the other way round but not finding any that match this direction (CSS → Figma Variable)
