[Feature]: IsAccessibleBrowser - Detect if Accessibility Support is Enabled

Describe the feature/enhancement you need

I need to be able to detect the presence of assistive technology in order to handle enabling some settings that help the application work with screen readers better.

The scenario/use case where you would use this feature

For users who are using a screen reader, we want to be able to detect that and toggle the appropriate settings.

How important is this request to you?

Impactful. My app's user experience would be significantly compromised without it.

Suggested implementation

In Electron, we were calling IsAccessibilitySupportEnabled which used a Chromium class IsAccessibleBrowser. We were also listening for the accessibility-support-changed event. To detect whether assistive technology was being used. Something similar to that would be ideal.

What does your app do? Is there a pending deadline for this request?

No response

Start by reviewing the referenced Electron app API, the accessibility-support-changed event, and Chromium's IsAccessibleBrowser implementation. Define the equivalent WebView2 detection and change-notification behavior, then verify that assistive-technology use can be detected and the requested settings can respond to it.
