 This cmdlet sends an invitation to the email addresses in invitations.csv. Additional features of this cmdlet include:
+
 - Customized text in the email message
 - Including a display name for the invited user

 Here we illustrate how to call the invitation API, in "app-only" mode, to get the redemption URL for the resource to which you are inviting the B2B user. The goal is to send a custom invitation email. The email can be composed with an HTTP client, so you can customize how it looks and send it through the Microsoft Graph API.
