Waveshare PN532. Cant read UID

Describe the bug I want to read the UID of some cards ( desfires, too ). I bought this Module. The module is a pn532 and as of #198 i suspected it could read the card

To Reproduce

            Pi.Init<BootstrapWiringPi>();
            while (true)
            {
                var device = new RFIDControllerMfrc522(Pi.Spi.Channel0,
                                                       spiFrequency: 500000,
                                                       Pi.Gpio[20]);
                // If a card is found
                var result = device.DetectCard();
                if (result == RFIDControllerMfrc522.Status.Error) continue;
                Console.WriteLine("Card detected");

                // Get the UID of the card
                var uidResponse = device.ReadCardUniqueId();
                Console.WriteLine($"Raw: {uidResponse.Data}");
                Console.WriteLine($"Card UID: {uidResponse.Data[0]}|{uidResponse.Data[1]}|{uidResponse.Data[2]}|{uidResponse.Data[3]}");
                Console.WriteLine($"UID String: {Encoding.UTF8.GetString(uidResponse.Data)}");
            }

No Output is printed to my console. I tried various other pins or frequencies... However the Demo Codes define like that.

#define _RESET_PIN                      (20)
#define _REQ_PIN                        (16)

#define _SPI_STATREAD                   (0x02)
#define _SPI_DATAWRITE                  (0x01)
#define _SPI_DATAREAD                   (0x03)
#define _SPI_READY                      (0x01)
#define _SPI_CHANNEL                    (0)
#define _NSS_PIN                        (4)

Expected behavior The Uid of the chip should be printed to the console

Devices

Pi4 2GB version
32-bit Pi OS ( Debian Buster )
Kernel 5.4

Additional context The examples apparently work:

$ python3 ~/tools/nfc/python/example_get_uid.py 
Found PN532 with firmware version: 1.6
Waiting for RFID/NFC card...
.Found card with UID: ['0x4', '0x33', '0x8b', '0x2', '0xa1', '0x5d', '0x80']

Any help on how to get this to work?
