Traefik sertificate file owner:group and privileges

I am trying to understand if it is important what owner:group and privileges should/can have certificate file "cert.pem". I generate this certificate and then mount it to docker compose traefik file.

tls:
  stores:
    default:
      defaultCertificate:
        certFile: "/certs.pem"
        keyFile: "/certs.pem"
  certificates:
    - certFile: "/certs.pem"
      keyFile: "/certs.pem"
