Private figma context in a plugin - I would love to be able to bundle a figma file with my plugin

It would be great if I could bundle my own Figma file inside my plugin. Then I could use my private Figma file as a place to store content, styles, variables… and my plugin could create new content based on my stored content.

Recently I needed to set superscript/subscript on text, however I don’t have access to opentype features from code… But I could set a text style in Figma, then my plugin could access this style and I could style text as I wanted. If I could bundle a pre-made style in my plugin, I wouldn’t have to have it predefined externally.
