How to support user submit rich text content into Sanity dataset outside of studio?

[Ali-Hussein-dev]

Hello everyone, I'm working on a Nextjs project which supports user to submit Rich Text Content to sanity dataset. I think I should put an Editor in the frontend, and transform the Editor content into sanity portable text.

I found this package @portabletext/editor but there is no documentation or examples. Is there any example for me to work through this feature?
