Can a SharePoint group be mapped and used instead of an Active Directory

[gerald4]

Hi, I got a question.

Is it possible to create, organise and map a sharepoint groups just how it would be done in an active directory?. A customer do not really update their ad. They rather would send an XML file with all users and roles in it. I want to know if i could import the file organise it and use it in flow. 

(i.e. If i would want to get and send a mail to a direct line manager of a user in powerautomate, I could easily use office365 connector since it picks it form the AD). Can I do that using a Sharepoint group

Not sure if you can process a XML file in a Flow, but for sure an Excel can be processed and I think what you need can be achieved
