Hi @Gary Schellhas ,
Good afternoon and thank you for your question. I was able to use https://graph.microsoft.com/v1.0/sites/{id}/onenote/notebooks on Graph Explorer and the OneNote Notebook under the Private Channel was showing. Make sure that you are using the ID of the Private Channel.
What I did was:
- GET https://graph.microsoft.com/v1.0/sites?search=private since the name of my channel is Private-Teams-Private-Channel and get the "id" of Private Channel
- Used the "id" of the Private Channel on GET https://graph.microsoft.com/v1.0/sites/{id}/onenote/notebooks and the OneNote notebook under Private Channel is showing on the response preview.
To add about the move, I only saw copy under the OneNote Notebooks:
