.fig Desing File Generation and Commenting Features in Figma Make

In Figma Make, it is possible to create code, but it seems that .fig design files cannot be generated. ref.How do I save/export a .fig file from Figma Make? | Figma Forum

Additionally, it appears that team members cannot comment on the preview in Figma Make.

Therefore, the collaboration feature, which is a key characteristic of Figma, is not available.

Are there any plans to release the ability to generate .fig files or a commenting feature?

Alternatively, are there any existing workarounds?

Thank you very much for your attention and assistance.
