this video is a good start.
Here are the firmwares.
https://dl.sipeed.com/shareURL/MAIX/MaixPy/release/master/maixpy_v0.6.2_27_g4d8d4fbf0
I tried this one, maixpy_v0.6.2_27_g4d8d4fbf0_openmv_kmodel_v4_with_ide_support
To work with the MaixPy IDE, the firmware needs to have "with_ide" in it.
This one also has kmodel, so it is convenient to run face find script with this firmware.
In MAxiPy IDE, for M1n board, choose Tools->Select Board ->Sipeed Maixduino
MaixPy IDE download

kflash_gui download

find face script and other scripts in this github repository
https://github.com/sipeed/MaixPy_scripts/blob/master/machine_vision/face_find/demo_find_face.py
On my laptop, the board creates com4 and com5. Use com4 for IDE and kflash
