How to find errata or package artifacts files under /var/lib/pulp on pulp-3 ?

Issue

Having some issue with repository metadata or (corrupted or missing) package, one needs to check the content of a repodata file (repomd.xml, updateinfo.xml etc.) or RPM package itself as stored on the disk on Satellite or Capsule. With pulp-2, the files were stored explicitly in /var/lib/pulp/published/yum/master/yum_distributor/REPO/TIMESTAMP/repodata/ (or packages) dir (and also behind symlink / URI path like/var/lib/pulp/published/yum/https/repos/RedHat/Library/content/dist/rhel8/8/x86_64/baseos/os).

pulp-3 does not follow that approach and stores the content under /var/lib/pulp/media/artifact directory. How to identify all or some specified repo metadata file or particular RPM there?
