Volvox Command line ICP not working

Hi together,

I am trying to use the command line component within the Volvox Add-On. Everything is working fine so far, however I can open or process files via the command line.
What I enter is:

-O D:/file_a.txt -O D:/file_b.txt -ICP

the error that is show: Unknown or misplaced command :"-ICP"
is ICP not supported by Volvox (with windows command line it works fine).

Someone has any experience with that issue or thoughts?
