Welcome to Microsoft Q&A!
Could you please provide a code sample to help us further check the problem for you?

2023-05-10T09:31:37.8833333+00:00 Hi @venki vicky ，
Is
web.InvokeScriptAsync()not getting the correct result? Have you tested your java script in browser(Edge) to get the correct result?If possible, could you please provide a reproducible example that would help to explain what your issue is?

2023-05-11T10:07:35.61+00:00 Your description is a bit confusing.
Which control do you need to use now? WebView2 or WebView? What's the real problem now? Could you please explain concisely.
