Need to Setup External Hard Drive

I need help with a simple task: I just want to plug in a hard drive (an 8 TB USB 3 drive that comes formatted as an NTFS drive). I have tried to connect this hard drive to my Turris Omnia, which seems to be able to “see” it but I can’t connect or mount the volume to access it as a network share.
I do not know much about how the Omnia works so any help you can provide to get this to work needs to be dumbed down, a lot! LOL
I know there is another thread (External Hard Drive NOT Showing Up) but I’m hoping there is a straight forward way to simply have this volume setup to save files within my LAN (I don’t want to implement some kludgey USB 2.0 Hub to make it work). Thanks!

Have you read the documentation ? For example
