Thanks,
I had been looking at other lines in fstab and these did not have a defaults
item, but once I added it the sudo mount -a works.
So this is what I have now:

PARTUUID=5ac54f4c-0819-4595-b457-f7d144df8076 /mnt/data ext4 defaults  0 0

And the listing of the mount point:
/mnt/data$ ll
total 24
drwxr-xr-x 3 root root  4096 2022-01-04 08:13 .
drwxr-xr-x 4 root root  4096 2022-01-03 23:26 ..
drwx------ 2 root root 16384 2022-01-03 21:48 lost+found

Follow-up questions:
1) What is this dir lost+found used for and is it neccessary?

2) In order to write files to this new disk I must use sudo, how can I allow a
regular user (me) to also create files and dirs here?
Do I have to sudo create a directory first and chmod it to 777?
