Get o365 reports using MS Graph

[vrush96]

I want a proper guidance where i can generate reports of o365 using MSGraph using app based authentication and also where can i find ready made scripts for the same.

Have you tried doing an online search? Crazy, right? :)
For example. this script by Tony leverages the client credentials flow to fetch the Teams activity report: https://github.com/12Knocksinna/Office365itpros/blob/master/ReportTeamsActivityGraph.PS1

Plenty of other examples are available in the Office365itpros GitHub repo, or in online searches.
