404 - Not found - Unable to add .ipynb as blogpost

[BirdiD]

Describe the bug Hello, I am trying to add a notebook to my wordpress blog using this shortcode

[git-github-jupyter url="https://github.com/cawoylel/nlp4all/blob/main/asr_tutorial.ipynb"]

I'm getting a 404 - Not found. When I replace the notebook by the readme.md file at the same GitHub repository, it works.

Have someone encountered something like this ?
