Everything will be fine
For all those QMK noobs like me: to use a keyboard config targetting a different mc:
qmk compile -e CONVERT_TO=helios
This automatically outputs UF2 and renames the pins of the config to match this mc.

Great!
Works as expected, recommended. Be sure to compile as .uf2 file

Works like a charm. Though note that this is an RP2040 based microcontroller, so although the pinout is compatible with the ProMicro, make sure qmk compile targets UF2 instead of the usual hex files for ProMicro boards. Also note that the additional first row pins on the Helios Controller. I placed mine a row off but luckily was able to still use it even after shorting VCC and Reset as opposed to Reset and GND.
