@Juan Carlos González Martín I am able to add a tab with my Powerapp as a website, but then it has this ugly black header (not properly iframe'd) with PowerApps menu button and settings wheel.

 

I wonder if it is possible to make configurable tab with manifest.json for my PowerApp?

 

UPDATE: I can report that it is possible to have fully iframed app if you use URL as indicated in this blogpost
