PWM capable pins on RAK3172


I am new to the RAK3172 + RUI3 ecosystem, and I love it so far. I never managed to build functional LoRa device prototypes so fast.

In my application I need some PWM output signals, and I was unable to find a clear answer in the docs (or figure out from the source code) which pins of the RAK3172 I can use (for analogWrite() and/or tone()). Any pointers would be appreciated!
