The Sharepoint input tool from Gallery recently changed configuration for app-only connection. The "Client Secret" is gone and the "Thumbprint" and "Private Key" are now required. The documentation doesn't seem to help documentation doesn't seem to have kept up. As I read it,

still refers to the old way and I need to know how to get "Thumbprint" and "Private Key"
Where do I get these values? Sharepoint Admin? Azure Admin? Other?
We need to configure to run in an unattended background process.
