Can't See NAS Drive when setting up Jellfin

[cdub]

I am a new user of the rasberry pi5, so I need everything explained like a child, but I am trying to learn.

I have setup JellyFin using Docker (whatever that is?) and mounted a share from my NAS Drive using the command below:

I created the folder diskstation with the command

sudo mkdir -p /media/diskstation

Then Run the command

sudo nano /etc/fstab

And added the line:

//192.168.10.200/jf /media/diskstation cifs guest,vers=1.0 0 0

Then saved and rebooted

I can see my NAS and the videos I want to view in Jellyfin in the file explorer on the PI, but when I am setting up the Jellyfin Server, I cannot see the folder diskstation when trying to add a folder in the setup wizard, I can see /media but its empty

Please can someone help me diagnose why I cannot see the diskstation folder

As I say I am a complete newbie and don't know very many commands as I am still learning.
