how to move notes from one profile to another on TabX?

Hi, I have two profiles/accounts on my TabX. Account 1 and Account 2. I'd like to move one file/notes from profile Account 1 to profile Account 2, and be able to write my notes in it. How can I do it?

I tried exporting/sharing the file, but I can only export/share it as PDF or .note file within the same profile on TabX. I tried using send2boox via internet browser, but I can only download it as PDF. And I want to continue taking notes in that file but on profile Account 2, instead of on profile Account 1. How to do it? How to move that file from profile Account 1 to profile Account 2 on TabX?
