Trying to setup a list to list article in current folder

[Osmoskour]

Hey,
How do you list the article in current folder? (cf. image)

Here I'm trying to have in the project page the list of all the article of the project I've written.

I tried to use slugs, but nothing seems to works for me.
Here's a link to the Repo I use if somebody have an idea:
https://github.com/Osmoskour/portfolio/tree/main

Thanks !
