Restrict access data in Power BI Report Server with Microsoft Access database

Hello,

I want to segregate data in Power BI report server. The database is an Access database.

"User 1 can only view the Perimeter" , "User 2 can only view the Perimeter 2".

I have seen some solutions in internet : 

- Row Level Security in cloud (report services)

- Using username() in MS SQL Server

but it doesn't work for Microsoft Access database in Power BI report server.

Can you help me please ?

Thanks in advance
