MangoFarm Custom Wallet with xPub address

MangoFarm is a wallet for Ravencoin (RVN). Koinly does not recognize this wallet. The wallet has a xPub address. I created a “custom” wallet for it but there is no way to enter a xPub address. It wants me to drag or drop files. The xPub address won’t paste and I can’t find a way or a place to add it. Any help would be appreciated.
