Web content filter also filter Webview or only Web browser?

Web content filter also filter Webview or only Web browser?

I am using ManageEngine MDM for Android. I can see a "web content filter" item in the Profile setup. I am wondering if all URLs blocked in this option also be blocked in Android System Webview or only on Chrome web browser? And if not, is there any way I can filter the content for Webview?
