Xiao nrf52840 writing to Flash - what am I missing?

Still comming up to speed. I’m currently struggling writing to flash. I believe the nrf52840 has 2MB onboard QSPI flash, but I can’t even get a simple read/write to work.

I am running the Seeed Studio nrf52840 -non mbed core/BSP. Some of the reading I have done suggests that I need to switch to the Adafruit Feather nfr52840 Express core, but for some reason, Arduino IDE will not let the board switch.

I would prefer to stay on the existing core/bsp as this was the LAST thing I had to bring up. I only need to write one 4 digit number to flash, very rarely. I am looking for the least invasive (and power efficient) way to accomplish that.

I have read many threads that started to look promising but hit dead ends. The most promising one ends in the need for a app_util_platform.h file that I cannot find (with confidence)

any bread crumbs? What am I missing. It really feels like it should not be this hard.
