I don't think these settings are accessible via JS.
Hi thanks for your post actually my goal is I just want to check the document is Reader-Enabled or not?
thanks in advance
I don't see a way to do it in the reference files, but maybe I'm missing
Enabling for reader restricts some features so you could always 'try' a known restricted function if it errors then the files enabled for reader.
Not tried it myself but it may work.
