How to use fenicsx (docker container) within VScodium?

I have been using a docker container since about 2 years now (still at FEniCSx 0.6 in there), and it still runs fine when I use a terminal.
I would like to use VScodium to run the files.py. I installed the docker extension in VScodium, and I can start the docker container from within VScodium, and even link a shell with it, execute the python code. However the default VScodium python’s interpreter is my system’s one, not the one of the docker container, so I cannot run the python files by clicking on the “Run” button.
I also cannot take any advantage of VScodium versus a regular gedit + terminal workflow, so there’s 0 incentive to use VScodium like this.
I wish to make VScodium use the python’s version that’s inside the docker container, but I don’t know how to do so. The official VScode pages explain how to do so from scratch, with some docker files, etc. but not with an already existing docker container.

This is still a VScodium question, not a DOLFINx/FEniCS question.
See for instance:

Thanks dokken. It looks like there’s a difference between VScodium and VScode regarding this topic, and things look quite dim for the former.

I decided to give (mini)conda a try and it worked quite effortlessly. I guess docker’s way will be easier in a couple of years from now.

I just have to update my code to work with 0.9 now.
