Rendering Sharepoint Modern Site Navigation Elements- reactjs?

# Bug Report

## Problem
InAppBrowser does not render Sharepoint Online Modern Sites as expected.

### What is expected to happen?
InAppBrowser should render the site fully without excluding elements. Note the Blue primary navbar and the site header 'Blank Modern Team Site' in the image below. This is how it should render.


### What does actually happen?
All Sharepoint sites visited via the InAppBrowser does not display the main navigation and site header. Note Nav and Site header missing from screenshot below.
