How to mount a disk on root for Kodi

I finally updated my media machine to Linux Mint 20.1. In the process switched from XMBC to Kodi.

I changed the disks that data is on. But I can’t find a way to get Kodi to see it. Except if I let the system mount it like a removable disk.

I have tried adding links in places Kodi does see, but it doesn’t seem to see links.

I have the disk mounted on /data, and it’s not showing in the root file system browser.

The disk shows in the browser, but doesn’t do anything.

I looked at the how to page, but I didn’t see any detailed permissions or anything that sounded like extra setup.

I don’t have any ideas, except to mount the smb share when I get that set up.

Any one know about this?
