I have an multi-tenant web application for different Azure accounts. I want to add a new custom directory role via PowerShell or Graph API so that I can automate things. I've walked through the reference for the Graph API but there was no any way to do this.

It is possible with PowerShell?
I also want create a new Azure Active Directory programmatically, if possible.
