Hello,

I cannot flash the nRF52840 Dongle using Programmer 4.3.0 with hex file sniffer_nrf52840dk_nrf52840_4.1.1.hex.

The option for writing is grayed out. =

- python: 3.9.0
- python3:
- nrfutil-nrfutil-device: 2.1.1

I was using sniffer_nrf52840dk_nrf52840_4.1.1.hex instead of sniffer_nrf52840dongle_nrf52840_4.1.1.hex
