I have some .djvu files that I annotated and saved as .okular files. Is there any way to export the annotations either to a pdf file, or just as text?

I have looked around and the standard solution seems to be to 'save as' a pdf but that does not seem to work with .okular files based on djvu files. When I try that I get message saying the annotations will be lost.

I would be grateful for any suggestions.
