Oh I see... I thought you wanted to set up your own VPN, as that's the usual use case for a VPN (e.g. connecting to a home server while not at home).

Looks like Windscribe have a Wireguard config generator so you could try that. https://windscribe.com/getconfig/wireguard. I don't have an account so I can't try it, but it may just generate a regular Wireguard config you can use with Wireguard directly, without having to use their app.
