Thanks a lot!
I did more homework in the mean time and I found a similar answer on the following thread: https://blender.stackexchange.com/questions/43060/loop-cut-and-slide-using-python with a small correction on this one: https://blender.stackexchange.com/questions/160739/loop-cut-and-slide-using-python-not-working/164563#164563.
Since then I found another issue I have not solved yet:
I do not know on which faces the loopcuts will come when I do it with python.
There is a parameter called edge_index that seems to control it, and I have not found a description of how to use it.
I have created the following script to try to investigate the issue, and there is too much data for me to have a conclusion I can use. Here is the script:
# this override code works!
