Does Acrobat still support nameddest parameter as open action?

I am trying to open a pdf at the named destination (nameddest). I have created a bookmark named Help. It's working fine on edge and chrome with URL(file:///C:/Users/asura/Downloads/Test.pdf#Help). But when I try nameddest from windows CMD. It doesn't work. However, page number works just fine. Am I missing something in nameddest? This doesn't work: 

"C:\Program Files\Adobe\Acrobat DC\Acrobat/Acrobat.exe" /A "nameddest=Help" "C:\Users\asur\Downloads\Test.pdf"

However, this works: 

"C:\Program Files\Adobe\Acrobat DC\Acrobat/Acrobat.exe" /A "page=7=OpenActions" "C:\Users\asur\Downloads\Test.pdf"
