Rights missing to configure Microsoft Azure Active Directory Single Sign-On (SSO) (Pro)

I installed Microsoft Azure Active Directory Single Sign-On (SSO) (Pro) extensions and followed the steps in the manual for the configuration.

Reaching step 10 I get the error
Failed to execute the [include] macro. Cause: [Current user [xwiki:XWiki...] doesn't have view rights on document [xwiki:AzureAD.AzureADConfigSheet]].

The logged in user should be the administrator with full rights. What am I missing?

I fixed it.
I first updated the extension to the latest version 1.7.2.
Then I added a trial license.
