SPI example for nRF52833 with nRF Connect SDK 2.3.0

Question

Dear Support Team, 
 
 I just started evaluating a nRF52833 DK board with the nRF Connect SDK 2.3.0. At this point I would like to start playing with the SPI but unfortunately I can't find any working example that I could use. 
 Could you please point me to a working example without using the deprecated configuration parameters? 
 
 Thank you very much in advance and all the best, 
 Viktor

Hi Marte! I managed to make the communication to the sensor work! I post the solution here so others can use it as well. Thanks again for the help!
