dynamic row level security with Azure Analysis Services and Azure AD security groups

Hi Everyone! 

Problem:

I want to use Azure AD Security groups for Dynamic Row Level Security in my Azure Analysis Services Tabular Model, but can't manage to import my security groups from Azure AD or even connect to the Azure AD. 

Security groups on AAD exist and I have a web application where my client can add and delete users to these groups (this automatically adds or removes them from the AAD) So far so good. 

In a next step I want to use these Security groups in my Azure Analysis Services Tabular Model for Dynamic Row Level Security.

Why am I doing this? Because my client wants to be able to create Power BI Reports on the basis of my tabular model and his staff should only be able to work with data in accordance to their security group. 

Background:

I am creating the Azure Analysis Services Tabular Model in Visual Studio 2019.

I use input data from an Azure SQL DB

I found plenty of solutions and ways to connect to on prem AD but I cannot manage to connect and use the Security Groups from my AAD. 

Any help, or hint or input is very much appreciated. 

Regards, 

M
