@crimx if you could kindly embed the code of https://github.com/shivaprsd/doqment to enable dark mode in this extension.

This plugin still does not officially support dark mode(v7.20.0). Do you have any related plans?😭😭😭

@crimx This is a small utility I wrote which can enable this feature in PDF.js. Integration should be straight-forward.

I use the same library to create doqment mentioned by @rehman-talha in a comment above.
