How to use the bitcore-lib-cash.URI function in bitcore-lib-cash

validateAddress(network: string, address: string): boolean {
      // Check if the input is a valid uri or address
      const URICash = BitcoreCash.URI;
      const AddressCash = BitcoreCash.Address;

       // Bip21 uri
      let uri, uriAddress;
      if (/^bitcoincash:|^bchtest:i/.test(address)) {
        if (URICash.isValid(address)) {
          uri = new URICash(address);
          uriAddress = uri.address.toString();
          return AddressCash.isValid(uriAddress, network);
        }
      }

       // Regular Address: try Bitcoin Cash
      return AddressCash.isValid(address, network);
    }
}
