Windows Defender Application Guard - Extension Within!

Hello there,

i've try to install a Chrome extension within the Application Guard Windows and got this message:

Ooops

Your organization blocks XXX (extension ID "xxxxxxx")

I understand why it's there, but not all extension are bad.  For exemple I would really like to have a adblocker in there.  Or give us the way to use "Add Tracking Protection Lists" like on IE (EasyList).  Because we would love to use WDAG precisely for site with a lot of these annoyance.  And now, without Adblocker inside WDAG, it's more or less useless

I've try these policies to install the extension without success:

-Allow users to trust files that open in Windows Defender Application Guard
-Allow files to download and save to the host operating system from Windows Defender Application Guard

Or please, permit us to white list the extension with the Microsoft Edge Policy:

-Allow specific extensions to be installed "xxxxxxx"

-Control which extensions cannot be installed "*"

or add a new policy like "Allow specific extensions to be installed in WDAG"

Thanks
