GL-B1300 vanilla OpenWrt 18: what simple front end for openvpn client config

I only miss the gui for uploading ovpn files. The wiki mentions this functionality is available in Openwrt 19. I'm not sure that's an option. What other option for uploading ovpn from a web UI are there?

There is indeed a page to upload ".opvn" files, and even edit them... did you install the proper package?
