Mounting Plex media drive in TrueNas

I have mounted a drive containing my media for Plex in the TrueNas plugin. However I am unable to successfully add it to a library. When I go to the location I mounted the drive, the folder is grayed out. I followed the instructions in Tom’s video for adding the library folder. I have all the permissions set as described. Any input would be great.

Thanks Dino
