Using Rubric option in Examy Package

Hello, I’m new here and still a beginner in the world of Typst. I came across an amazing yet simple package called Examy. I’m using it to create assessments. In the manual, one of the options for #questions( ) is rubric however in section 10.17 it says

A grading rubric (accepted, but not yet rendered).

I’m assuming its something that’s still being developed? Does anyone know how I can help develop it?
