[Feature]: Adding custom text to PermissionRequested prompt

Describe the feature/enhancement you need

I wanted to add custom text to the clipboard read permission prompt, but there is no way of doing this with the built in prompt. I know I could make a custom prompt, but that seems really unnecessary when all I want to do is have a custom message.

The scenario/use case where you would use this feature

This would be used to add some more information/context to the permission requested prompts, like telling users a website could potentially be reading sensitive information from the clipboard, without needing to make a whole custom prompt.

How important is this request to you?

Nice to have. There are other ways to tackle this, but having official API support would be beneficial.

Suggested implementation

A string property could be added to the CoreWebView2PermissionRequestedEventArgs that could be set to the message you want added to the prompt.

The event args is already being used to determine whether or not the WebView2 prompt is displayed (by setting State), so I think it could also be used to pass on the custom message to the prompt.

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

No response

Start with the CoreWebView2PermissionRequestedEventArgs API described in the issue and investigate how WebView2 permission prompts consume its State. No implementation files or tests are identified in the payload. Done would mean an official way to supply custom text for the clipboard read permission prompt, with documented behavior and coverage.
