Reference another notebook in a notebook

Question

I am using mkdocs to build my static website. The tree of my project is the following:

docs/
├── index.md
├── numerical_methods
│   └── ode
│       ├── explicit_euler.ipynb
│       └── implicit_euler.ipynb
└── numerical_methods.md

I want add a link to redirect from explicit_euler.ipynb to implicit_euler.ipynb. I added this part [the backward Euler method](./numerical_methods/ode/implicit_euler.ipynb) in explicit_euler.ipynb and it is not redirecting to the other notebook.

If it can help, mkdocs.yml:
