Edit presentation with remote API

Edit presentation with remote API

Hello,
I wanted to use Zoho Remote API to edit office documents in my tool.
I use this API https://apihelp.wiki.zoho.com/Open-Document.html
It works fine with documents and spreadsheets . But when i try to open a presentation (ppt or pptx) it is opened only for view. It is not possible to edit.
I send same request as for documents or spreadsheets. Only the host is different show.zoho.com . output=url (same as for documents).
Why are presentations opened in view mode? Is edit mode supported in remote API for presentations?
Thanks.
