hyperref links to first appearance of bibliography entry when using bibunits

Question

I am working on a thesis that has a bibliography per chapter using natbib and bibunits. Some citations appear in different chapters. hyperref appears to always link to the page of the first occurrence of the specific label. How can I make sure that hyperref 'knows' that it should instead link to the specific reference in the chapter-specific bibliography?

A minimum working example that reproduces these errors:

% main.tex
\documentclass{book}
\usepackage[sort&compress,numbers,sectionbib]{natbib}
\usepackage[globalcitecopy]{bibunits}
\usepackage{hyperref}
\bibliographyunit[\chapter]
\defaultbibliographystyle{plain}
\defaultbibliography{bibliography}

\begin{document}
  \include{chapter1}
  \include{chapter2}
\end{document}

% chapter1.tex
\chapter{}
\citep{article}
\putbib

% chapter2.tex
\chapter{}
\citep{article}
\putbib

% bibliography.bib
@article{article,
    author={Dummy},
    title={Dummy},
    year={2021},
    journal={Dummy}
}

Answer 1

You can change the destination names and make them unique. But you should then also use the bookmark package to avoid problems with the bookmarks.

\documentclass{book}
\usepackage[sort&compress,numbers,sectionbib]{natbib}
\usepackage[globalcitecopy]{bibunits}
\usepackage{bookmark}
\bibliographyunit[\chapter]
\defaultbibliographystyle{plain}
\defaultbibliography{bibliography}

\renewcommand*{\HyperDestNameFilter}[1]{#1-\thechapter}

\begin{document}
  \include{chapter1}
  
  \include{chapter2}
\end{document}
