I am enjoying working in the dark mode with NativeOverleaf. I like to download the dark version of the PDF as well. How can I do it?

As in the above discussion, people would like to have the dark-mode filter on the PDF viewer in the PDF file itself. Hence, the PDF file itself would need to be changed directly. If anybody could look into this, it would be much appreciated!
