Revtex and doi package incompatibility

Question

I'm using revtex-4-2 to write my manuscript and want to include clickable links (doi) in my bibliography. If I use the doi package, I get an error (LaTeX Error: Command \doi already defined.) even though the compilation seems ok. How do I fix this? Here is my MWE (adapted from Overleaf template):

\documentclass[prb,floatfix,reprint]{revtex4-2}
\usepackage{doi}

\begin{document}
\preprint{APS/123-QED}

\title{paper title}

\author{Ann Author}

\begin{abstract}

Answer 1

revtex itself has a built-in mechanism for inserting DOIs into bibliographies, as part of that it defines its own \doi macro which conflicts with the \doi macro that the doi package defines, making the two packages incompatible.

As revtex will already add DOI links in the bibliography simply omitting the doi package should be sufficient in most cases.
