3. Following [this tutorial page](https://learn.microsoft.com/en-us/graph/tutorials/powershell-app-only?tabs=linux-macos&tutorial-step=1#register-application-for-app-only-authentication)
I've created the following utility scripts to help with this process:
1. [`Create-Cert`](Create-Cert.ps1) -
Create a self-signed certificate and load it into the .NET
cert-store (see Load-Cert next).
2. [`Load-Cert`](Load-Cert.ps1) -
Load certificate files into the local .NET cert-store.
3. [`Connect-AppCert`](Connect-AppCert.ps1) -
This will be used to establish a new app connection.
