how to use RFM95 with Blue pill SPI2

[fizga]

hello,
I am a beginner with STM32s and electronics is my hobby.
someone could tell me how to use an RFM95 on the SPI2 of a blue pill, I have already used the RFM95 with arduinos but never with blue pill, an example of code would be ideal to understand.
while doing research on the net I saw some posts on how to declare specific pins but it is not clear to me.
