I have a .NET web application where I am using the app-owns data approach to embed PowerBI reports to allow users registered in the Azure AD of my organization to view and use the reports, without them needing a PowerBI license.
Is there a way to do the same thing in Power Apps ?
I created a Power App and was able to embed a PowerBI Report in the app. Please refer to the documentation: Embed Power BI report in Power Apps (linkedin.com) But since you asked that you want to allow users to view the report without PowerBI License, that is actually not feasible. The user needs to have a valid PowerBI License to view the report in the Power App even if you give the necessary permissions. Please go through reference for clarification: Solved: Re: Share Apps to everyone that don't have account - Power Platform Community (microsoft.com)
