When AreBrowserExtensionsEnabled is set to TRUE, new extensions can be added to user profile and used. AreBrowserExtensionsEnabled is default to be FALSE, in this case, new extensions can't be installed, and already installed extension won't be available to use in user profile. If connecting to an already running environment with a different value for AreBrowserExtensionsEnabled property, it will fail with HRESULT_FROM_WIN32(ERROR_INVALID_STATE). See ICoreWebView2BrowserExtension for Extensions API details.
