Description of problem:
When I try to use U2F Yubikey as authentication for a sudo command and configure it appropriately in the /etc/pam.d/, then every time I issue `sudo` command, then I get a denial from SELinux and authentication request for U2F is skipped and goes directly to password prompt
SELinux is preventing polkit-agent-he from 'open' accesses on the chr_file /dev/hidraw2.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that polkit-agent-he should be allowed open access on the hidraw2 chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'polkit-agent-he' --raw | audit2allow -M my-polkitagenthe
# semodule -X 300 -i my-polkitagenthe.pp
