Addressing SPI pins for the ATMEGA4809 using the Arduino-LMCI library

Hello everyone.

I'm trying to run the example arduino-lmic/examples/ttn-abp/ttn-abp.ino at master · mcci-catena/arduino-lmic · GitHub to send a "Hello World" via LoRa, but I'm having trouble.

I noticed there's no clock signal and no signals on the MOSI and MISO pins either.

The code isn't allowing communication.

Since I'm using the ATMEGA4809, perhaps the #include <lmic.h> library is assigning pins that aren't designated by the ATMEGA4809. Could someone tell me how to assign the pins correctly for the ATMEGA4809?

NSS 7
SCK 6
MISO 5
MOSI 4
NRESET 40

 * This example sends a valid LoRaWAN packet with payload "Hello,
 * world!", using frequency and encryption settings matching those of
 * the The Things Network.
 *
 * This uses ABP (Activation-by-personalisation), where a DevAddr and
 * Session keys are preconfigured (unlike OTAA, where a DevEUI and
 * application key is configured, while the DevAddr and session keys are
 * assigned/generated in the over-the-air-activation procedure).
 *
 * Note: LoRaWAN per sub-band duty-cycle limitation is enforced (1% in
 * g1, 0.1% in g2), but not the TTN fair usage policy (which is probably
 * violated by this sketch when left running for longer)!
 *
 * To use this sketch, first register your application and device with
 * the things network, to set or generate a DevAddr, NwkSKey and
 * AppSKey. Each device should have their own unique values for these
 * fields.
 *
 * Do not forget to define the radio type correctly in
 * arduino-lmic/project_config/lmic_project_config.h or from your BOARDS.txt.
