Diskover crawler cannot crawl '0700 root root' directories

[echogram]

There is a major directory tree (/var/lib/docker) that I want diskover to crawl (so I can monitor volume growth) but the permissions of most of the top level directories in it are:
drwx------ root root

The diskover container will not start as PUID=0 and I do not want to change the permissions of the directory tree. Since there is no group access, I cannot resolve this by adding user 1000 to a group 0 (which I would not to do anyway).

Is there a solution to this using cap_add of CAP_DAC_READ_SEARCH in the docker-compose.yml?

Expected Behavior

Should be able to crawl 0700 root root directories

Current Behavior

0700 root root directories are skipped

Steps to Reproduce

Direct crawler to crawl over a directory tree containing 0700 root root directories

**CPU architecture:x86_64
**How docker service was installed: Ubuntu 20.04 repos
