nRF5_SDK_14.2.0_17b948a Trying to compile example "record_text" keeps telling me it cannot find "nrf.peripherals.h"

Trying to compile using the on-line Mbed compiler.  I keep getting cannot find "nrf.perhiperals.h", and I cannot locate it either.

Possible someone can point me in the right direction

Thank you
