Where is the PDF viewing/editing function in Desktop Editors v.8.2.2?

Regarding the recently added PDF (viewing, editing) functionality, is this built-in to the OnlyOffice app?
I don’t see any option for it.
I am using v.8.2.2 of Desktop Editors.

I just opened a PDF document directly in Docs (DT Editors 8.2.2) but have not found any setting in the toolbar that provides the option to edit it.

What do I have to do to put the document into ‘edit mode’?

Thanks.

Hello @mk7z,
You need to click Edit PDF icon of the interface
edit pdf

After that you should be able to see the editing options shown on the screenshot below:

@DmitriiV… Thanks. I had already tried that. It didn’t work. (I thought the PDF viewer/editor might be a separate plug-in I needed to install.)

The PDF document in question has two sections. A form fill-in section and an instructions section below it.

Text in the instructions section can be ‘selected’ and dealt with normally.

In the form fill-in section I can select and copy text (i.e., the fields ‘labels’). The copied text pastes into a text editor but with loss of formatting. I can also perform some of OnlyOffice’s editing functions on the text. But when I click into the blank ‘fill in’ areas nothing happens. I can’t enter any text.

Do you have any idea why?
