Xiao nRF52840 PlatformIO install issue

[jhmaloney]

Thank you for adding PlatformIO support for the Xiao nRF52840 to n-able.

Compiling is successful but using the "-t upload" option fails with this error:

Usage: nrfutil [OPTIONS] COMMAND [ARGS]...
Try 'nrfutil --help' for help.

Error: No such command 'pkg'.
*** [.pio/build/xiao-nf52sense/firmware.zip] Error 2

I tried dragging the firmware.hex from .pio/build/xiao-nf52sense/ onto the Xiao nRF52840 but it is not recognized.

What am I doing wrong?
