How to embedded Power BI App in Sharepoint

Using the embed function (on the right side of the picture) in SharePoint with the web URL of the app the browser says that for security reasons it is not authorized to open the website inside of a sharepoint page.

Using the Power BI function to connect to the app (on the left side of the picture) with the url of the app is not working.

here you can find documentation about embedding reports (but not apps) :
- https://learn.microsoft.com/en-us/power-bi/collaborate-share/service-embed-report-spo

- https://learn.microsoft.com/en-us/power-bi/collaborate-share/service-embed-secure

As far as I know it is not possible today to do that

the question has also been asked here https://community.powerbi.com/t5/Service/Embed-an-APP-in-Sharepoint-Online/m-p/3147599
