Wake Up Via Internal Timer Sodaq ONE

Hi, does anyone have a example code to put the board to sleep and wake it up via internal timer interrupt 5 mins.
Appreciate the help. I am new in programming microcontrollers

thank you.

Gabriel has some nice samples:

Thank you! Axel, I will try these examples!

Are there any other alternatives or a way to say “in the next 5 mins” as opposed to having to specify an exact date and set the match on that date?

RTCZero alarms seem very complicated to simply have an interrupt “in 5 minutes”
