How to solve failure in plugging external DVD driver in Ubuntu 20.04?

I have bought an external DVD driver but, after plugging (or booting with the unit already plugged) I see the unit listed in the resources of the computer but I cannot access it: If I try to access the driver via VLC, I get the error VLC is unable to open the MRL 'cdda:///dev/sr0'. The content of fstab is: $ cat /etc/fstab # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # # / was on /dev/nvme0n1p2 during installation UUID=341faa1b-4e49-49d7-85a4-e33acecb2212 / ext4 errors=remount-ro 0 1 # /boot/efi was on /dev/nvme0n1p1 during installation UUID=24D6-7429 /boot/efi vfat umask=0077 0 1 /swapfile none swap sw 0 0 What is the right way to plug a DVD in Ubuntu 20.04? Is it a problem with the driver (I need to buy another brand more Linux-prone)? Or do I need to change the permission of the driver with some sudo commands? After I plug the DVD driver I get: $ ls -lt | less | grep sr0 lrwxrwxrwx 1 root root 3 May 27 21:15 cdrom -> sr0 lrwxrwxrwx 1 root root 3 May 27 21:15 cdrw -> sr0 lrwxrwxrwx 1 root root 3 May 27 21:15 dvd -> sr0 lrwxrwxrwx 1 root root 3 May 27 21:15 dvdrw -> sr0 brw-rw----+ 1 root cdrom 11, 0 May 27 21:15 sr0 Thank you
