What are the available values for "documentAccess" in manifest.json?

I am working on a plugin that is calling a function that requires access to other pages in the Figma file.

What are the allowed values for documentAccess in the manifest.json? Do I just put an empty string for it?

Currently, the documentAccess property only accepts dynamic-page value.

Does this mean that if a plugin requires access to other pages I would need to set documentAccess to dynamic-page and then update all usages of functions that are deprecated to use their async equivalent?
E.G.) getLocalPaintStylesgetLocalPaintStylesAsync.

Yes, if you add a documentAccess field to your manifest, you will need to use async methods.
