PDF Embed API & Microsoft Teams App

I added an application created with Angular 16 as a custom app in Teams.
I'm using the PDF Embedded Api to display PDF files, but when I display them in "full screen mode" in the Teams app, I can't press the search or exit buttons in the top menu.

The same operations can be performed without any problems in the browser version of Teams.

Are there any other users facing issues like this?
