Two way communication between two STM32F303 Nucleo-64 boards using nRF24 Transmitter-Receiver

We need a small project that implements only a simple communication between two STM32F303 boards with nRF24 Transmitter-Receiver. We would like to send a struct from one board to another and another struct back.

The struct should be something like:

typedef struct
{
uint32_t DataFlag;
uint16_t dataA;
uint16_t dataB;
}DataPack;

the project should be built with STM32CubeIDE and C++

Please see attachement of the pin setup.
