Understanding the use of '@' in groq for reading fields outside of the reference context.

Hi!In groq, while resolving a reference, I want to read a field outside of the reference context. From the 'Query Cheat Sheet - GROQ' I understand the '@' to let me do this, but I am not able to make it work. Does the '@' not work as documented, or am I misunderstanding something?

In the example below I am trying to read the 'isSignLanguage'-field from inside 'rightsList'. See image from Vision:

What do you get if you do

All the content of the document referred to in rightsList:

@

returns the current scope. I think you may want

^

to access the parent scope (you may need to chain two in your case).

Thanks!
