Hi， @Mannai 

Please refer to this official document.

Embed a report in a secure portal or website 

After the user has signed in, the report opens, showing the data and allowing page navigation and filter setting. Only users who have view permission can see the report in Power BI. All row-level security (RLS) rules are also applied. Lastly, the user needs to be correctly licensed – either they need a Power BI Pro or Premium Per User (PPU) license, or the report must be in a workspace that is in a Power BI Premium capacity. The user needs to sign in each time they open a new browser window. However, once signed in, other reports load automatically.

The Embed option doesn't automatically permit users to view the report. View permissions are set in the Power BI service.In the Power BI service, you can share embedded reports with users requiring access. If you're using a Microsoft 365 Group, you can list the user as a workspace member. For more information, see how to manage your workspace in Power BI and Microsoft 365.
