Power Bi Embed With Sharepoint

I was working on POC where I was trying to embed power bi report ( which is not publicly shared) with sharepoint. I had created a provider hosted app and created an app in Azure AD and gave permission on the report to org id. I could see the reports on the sharepoint page but when I share page with external user, for example outlook account and logged in with the external id I am not able to see the report. I was not able to provide access on power bi reports to outlook, hotmail, gmail etc except my organization accounts. Can you please suggest on how to achieve this. Is there any alternative method.
