InAppBrowser not in full screen

hi, I have to show a link to a pdf file in my application.
The iframe works but it does not scale to the correct width file.

With inAppBrowser works but it is always and only as wide as the entire view, there is a way to reduce it? in particular width: 100% height: 90% (so that you see the header behind)

I’m looking for this too.

It is incredible after so many years there is still no way to show the inAppBrowser, for example, configuring that its height is not fullscreen to be able to put a menu of buttons under the inAppBrowser
