Not able to link BrowserView accessibility tree to the main accessibility tree

Problem description

I have a use case where I have embedded a browser view inside browser window. Since browser view is not part of the DOM hierarchy hence the accessibility tree is not linked to the main window(parent browser window).

So my use case is to link the browser view accessibility tree with the main window accessibility tree such that screen readers(JAWS/NVDA) are able to enumerate all the possible landmarks for navigation

** Expected Behavior**

There should be a way to link the accessibility tree of browser view to the main AX tree.

Actual Behavior

No way to link the accessibility tree of browser view.
