About making money approval

When we publish a website from someone else in our app, can we not get Monetization approval for that app

Your app can’t be approved if you create only webview app. It’s also against Google Policy to use any website in app without permission and you also can’t use ads in it.

Adding one point more.
If website is yours and contains ads any then also you can’t put any mobile ads on app just show website to user.
