MineOS + TrueNAS mapping mount point permissions

I’ve installed MineOS on TrueNAS and its working which is great - but I wanted a way to easily access the file system of the plugin.

It seems there are two good ways:
Mount a folder in an existing Datapool to /var/games/minecraft
access /mnt/dataset/iocage/jails/mc/root/var/games/minecraft

What I want is my user with uid 1000 to have rw access to these files without causing the error 23 I have when trying to save-all or change the jar.

Does anyone have the perfect recipe for this situation?
