How to remotely connect to a shared folder on Raspberry Pi via OpenVPN?

Question

linux

Good day, dear ones!
I want to make it so that from a smartphone, using an openvpn connection, connect to a shared folder on a raspberry.
Tell me please, in which direction to dig, to solve such a problem?
What has already been done:
1. Received a static IP from the provider.
2. Raspberry is connected to Mikrotik; has its own permanent internal IP address. (192.168.10.10) Using port forwarding 22, I can SSH from anywhere to the raspberry using a static IP:22.
3. Samba is configured on the raspberry and the folder is shared on the network. You can see it on your home computer, from your smartphone (if the connection goes through home wifi) you can also see this folder - using the ES File Explorer application.
4. OpenVPN configured on Mikrotik. I easily connect from my smartphone and get a different internal IP address (10.10.10.10) than my home network.
