How to show page breaks on word document with FileOpener ionic 4

Hi, i am using FileOpener: to load and show a word document on Ionic 4. I am facing two problems:
a) The page breaks are not shown. It does not happen the same ,like with DcomentViewer: ,where the page breaks are shown . Unfortunately the DocumentViewer works only for pdf files and not with word documents. I do not know , is there a way to use DocumentViewer with word documents as well? That would solve the problem.
Is there an option to show this,please?
b) When i pinch out ,the DocumentViewer disappears.

I was wondering if you could help me,please?
Thank you in advance.
