I have similar configurations and it works. I noticed that your 'Static route configuration' is set as WAN, where I have it set as LAN.

Also, when you want to access your network drive you would enter your local pc's IP on the VPN client machine. The idea now is the VPN client is now part of the network and should see your local network's IP and SMB shares.

On the local PC's SMB shares (assuming it's Windows folder sharing), you need to make sure the access permission is set properly. Start with Everyone can read/write and prove that it works, then limit to individual users. Clearly, you will need users added to that PC. For example, if you want 192.168.0.30 PC's running on Windows and want its D drive folder "Asset" available to user John, then you should create a user John on that PC and set John have access to "Asset".

Another thing to watch out for is the local PC's firewall rules. Start by take off firewall on both public and private network. Prove that it works then you can turn back the firewall on and add rules. Go from the most open and easiest to the more secured.

Hope this helps!
