Ideas on how to automate the documentation of function return types.

[ccsenter]

Summary

Our Preact library that we are documenting with Storybook inevitably includes hooks (and utility functions) that we would want to document together with our components.
The problem in documenting these functions (hooks, utility functions) is that while the properties of the hook (the argument of the hook function) could be documented by simply using a CSF story file with a default story (creating a wrapper component around the hook and exposing the hook function arguments as props on this wrapper component) and then connecting this to an MDX file (and just use ArgTypes or other DocBlocks)) documenting the return type seems to be more challenging.
What would be a reasonable approach on incorporating the return type into my storybook documentation without just manually writing documentation for them?
I'm looking for a way that would leverage existing components in Storybook so that when I manually update the hook source, the documentation would just be there?

We are using Preact, SB 8.3.6 and Vite as the builder.
