Thanks all for your comments and answers, I’ve just tests the keyboard and it seems to work pretty fine, I’m really happy, I didn’t expect to get something working directly!
As a reminder, here is the commands I’ve used to get the firmware to copy:
# Install the required compiler
sudo apt install gcc-arm-none-eabi
# Enter in the virtual environment
. ~/.virtualenvs/qmk/bin/activate.fish
# Check the keyboard
qmk list-keyboards | grep sofle
# Check the keymaps
qmk list-keymaps -kb sofle_choc
# Compile
qmk flash -kb sofle_choc -km via -e CONVERT_TO=promicro_rp2040
