OpenVPN and file access

Hello all. I have installed OpenVPN on TrueNAS and can successfully connect using the client on my laptop at home. But I’m new to this and I was thinking this was a way to access files stored on my SMB share in TrueNAS. If that’s not the case then this was certainly pointless, but if that is something I can do I need to know what else I need to install. Do I need a jail on TrueNAS tied to my SMB share? Any and all help appreciated.
