Github private repository example
If your notebook is in Github private repository, Github personal access token is needed. Create a token at https://github.com/settings/tokens by clicking Generate new token button.

Enter the URL in Notebook URL field in macro UI. Once saved and published, notebook will be rendered as shown below:
