Azure setup for NC OneDrive integration

Hello all
Having a really blond moment and can’t seem to see the wood for the trees.
I am attempting to setup OneDrive integration (3.0.0) app on my NC (27.0.1) server.
I am having issues with the Azure setup for this.
Just wondering if anyone can point me to a detailed setup for this as I just can’t seem to follow/understand how/what to do to get this working.
