Librem One Tunnel on other devices

Has anyone setup Librem One tunnel on a different type of device, such as a NAS, for instance?

My device has an OpenVPN option, but it wants either a .ovpn file OR server address, port, whether it is UPD or TCP and a CA Certificate.

Set it up on a Linux with NetworkManager or the phone app, then export the config from there.
It’s just OEM from PrivateInternetAccess so any device with OpenVPN will work.

Great - thank you for the quick response!
