    image: openvpn
    networks:
      - net

  app:
    image: myapp
    networks:
      - net

I found it by myself. I can add myapp to the same network of openvpn by adding a config to myapp service.

network_mode: "service:openvpn"

By this, I cannot expose the port on myapp but I can expose ports in openvpn to access myapp as they are in the same network
