How do “published” modules import helper functions from a previously imported published module?

The docs say:

Published modules cannot leverage auto-imports for assets within their runtime directory. Instead, they have to import them explicitly from #imports or alike.

All my attempts have resulted in

• WARN Duplicated imports
• ERROR Vue app aliases are not allowed at runtime
• ERROR RollupError
