Embed report using PBI Report Server

I work on a product that is installed on-premises. Data is in SSAS and SQL Server. I understand that PBI Embedded Analytics can be used and there is a Microsoft provided Angular package available to facilitate this.

Questions are:

1. Can I use on-premises PBI Report Server to embed reports in an Angular app?
2. How will authentication work? User should not be prompted for any additional login.
3. If PBI Report Server allows embedding reports, then is there any Angular package that can facilitate this?
