Onenote notebook, sections and page IDs permanent?

Question

I'm using the API here: https://learn.microsoft.com/en-us/graph/onenote-get-content#resource-paths-for-get-requests to get and write information to pages.

I was wondering if anybody knows whether the IDs retrieved through the API changes. I found this Converting between OneNote Ids for internal vs HTML links?, which says that the runtime IDs change. But I tried a few calls and doesn't seem to change, so I'm very confused.

I'm wondering if there is a key like reference for Onenote objects, as like a google sheet where each sheet has a unique key and that never changes. I'm looking for an anchor like that.
