Camera permission popup is not opening from WKWebView. WKWebView is not allowing camera access

I am working on a video conference app using webRTC and when I try to open the url on iOS web view(WKWebView) then its not showing camera permission popup. If I run the url in Safari browser then permission popup is displaying. I want to create a web app for video calling. I have tried below solutions but didn't work.
